Where Are Lithium Ion Batteries Made?

It was first proposed in 1970, now it is using in very things like- mobile phones, airplanes, and cars, etc. It is made of four compounds, the first one is cathode which operates the capacity and voltage of the battery. The second one is an anode that enables the electric current that flows through an external circuit. It is easier than you can buy Lithium Ion Solar Battery from Firemountainsolar. It is developed by Argonne National Laboratory. It is a reliable source to carry out any kind of solar kit.

1. Is it bad to let your Lithium-Ion battery completely die?

Yes and no... LI-Ion batteries have a (generally) fixed amount of power cycles. So, for example if you run it down to 50%, and charge it 1000 times before the battery dies, you would get around 500 charges from 0% to 100 instead from the same battery. It's the overall power in/out that determines it's life (again, in general terms) That said, it's generally not good to run those batteries down to zero all the time....

2. What is the best way to take care of a Lithium Ion Laptop Battery?

Basic: Reducing charging times,laptop battery has life of 300-500 normal charging times. Reducing unnecessary power supply to get longest life. ( cut usb powered devices....)

3. Is it good to fully discharge lithium ion batteries?

It is healthy once in a month in order to reset and recalibrate the BMS. But it is detrimental to battery life on routine basis

4. is lithium orotate or lithium aspartate best for mood swings?

alphacalm,also max stress from qnlabs.com.Drugs are very harmful to the body the reason why people do not live past 100 is because no one took drugs 2,000 years ago they lived hundreds of years so stick with holistic methods

5. is the life span of a dewalt lithium battery longer than regular 18 volt battery?

That is yes for sure. I used an 18 volt lithium battery powered portable drill for about a year. It needed recharging about every 10 to 12 hours. (life expectancy about 400 hours) When I wore-out the drill, I bought an 18 volt drill with a regular battery. It drains in about 6 hours. (so I have to recharge it every day - and each time it is taking longer to recharge -- I figure it has a life expectancy of about 200 hours and then it will not take a recharge)

6. If the half-lives of hydrogen, helium, and lithium are 12 years, a millisecond, and 24 hours respectively, how could the cosmic background radiation possibly come from an event 13.8 billion years ago?

Microwave background radiation was emitted by the hot primordial matter composed only from light elements, when the temperatur dropped down to about 3000 Kelvins allowing formation of atoms and making the matter sufficiently transparent for photons to allow them free propagation in space. It has nothing to do with the radioactive decays of those light nuclei (only tritium eventually). Cosmic Microwave Background: Remnant of the Big Bang.

7. Emergence of crucial interphase in lithium-ion batteries is observed by researchers –

What happens in a lithium-ion battery when it first starts running? A complex series of events, it turns out - from electrolytic ion reorganization to a riot of chemical reactions. To explore this early part of a battery's life, researchers in the US have monitored a battery's chemical evolution at the electrode surface. Their work could lead to improved battery design by targeting the early stages of device operation. The solid-electrolyte interphase is the solid gunk that materializes around the anode. Borne from the decomposition of the electrolyte, it is crucial for preventing further electrolyte degradation by blocking electrons while allowing lithium ions to pass through to complete the electrical circuit. The solid-electrolyte interphase does not appear immediately. When a lithium ion battery first charges up, the anode repels anions and attracts positive lithium ions, separating oppositely charged ions into two distinct layers. This electric double layer dictates the eventual composition and structure of the solid-electrolyte interphase. Vital as it may be, the electric double layer had only been speculated and rarely observed until recently. Now team of researchers at the Pacific Northwest National Laboratory and the Army Research Laboratory led by Zihua Zhu has provided direct experimental evidence for the double layer using a homebuilt secondary ion mass spectrometer, a tool that analyzes ionized particles ejected from surfaces. The patented instrument can identify the chemical makeup in layers as thin as several nanometres. Moreover, it can probe liquids - such as battery electrolytes - under vacuum conditions. To carry out the measurement, the researchers assemble a vacuum-compatible battery by encapsulating a liquid electrolyte with a copper electrode followed by a silicon nitride barrier. Mass spectrometric analysis begins when a focused beam of bismuth ions drills into the silicon nitride layer, kicking up ions and leaving behind a small hole. The hole depth can be precisely controlled, and the corresponding ejected material is monitored as a function of depth. When the bismuth ion drill reaches the underlying liquid layer, the liquid surface tension and the small hole size prevent the electrolyte from "geysering" into the high vacuum environment. However, a few liquid particles do escape to be detected and analyzed. "Our technique has excellent depth resolution and molecular recognition right at the solid-liquid interface," says Zhu. "These are the advantages over rival techniques, such as transmission electron microscopy." The measurements paint a picture of how the solid-electrolyte interphase emerges. The electric double layer of positive and negative ions morphs into the solid-electrolyte interphase comprising a dense, lithium oxide-rich inner layer and a loose, organic outer layer. Understanding the electric double layer provides insight into how to manipulate the solid-electrolyte interphase. For example, to incorporate fluorine into the inner layer for higher lithium ion mobility, adding fluorine-containing anions into the electrolyte will not work well because the anions will be repelled away from the anode. Zhu's experiments suggest that introducing neutral, fluorinated solvent species instead of anions can bypass the electrical repulsion. This study of the initial formation of the solid-electrolyte interphase "allows scientists to design new interphases to improve battery performance," says Zhu. In the future, the researchers want to apply the same liquid-based mass spectrometry to study the cathode, as well as different electrode materials such as silicon. Moreover, the close-up discovery of layers in the solid-electrolyte interphase presents new electrifying possibilities for further exploration in the same battery system. Several fundamental questions still remain, and Zhu and his team are already on the chase. This work is reported in Nature Nanotechnology.

In 2020, China's Shipments of Energy Storage Lithium Batteries Were 16gwh, Including 6.6gwh of Elect
abstract, accounting for 41%, and 7.4gwh of communication energy storage, accounting for 46%.According to the preliminary statistics of the Institute of lithium batteries of the Institute of advanced industry and Research (GGII), , accounting for 41%, 7.4gwh of communication energy storage, accounting for 46%, and others including lithium batteries for urban rail transit, industry and other fields.In 2020, electric energy storage is still in the early stage of industrialization. Despite the intensive introduction of policies to cultivate the energy storage market, problems such as low-cost bidding, security concerns and fuzzy business model have not been eliminated. Therefore, the development of the industry still needs a period of time. With the support of a new round of favorable factors such as new energy grid connection, power auxiliary compensation policy and power price adjustment, GGII believes that China's power energy storage lithium batteries will have huge development space in 2021.In 2020, China's communication lithium battery shipments were lower than expected, mainly due to the sharp decline in the demand for overseas communication lithium batteries and the lower than expected number of new 5g base stations in China. The price of base station lithium battery is in a downward trend as a whole, the profitability of small and medium-sized enterprises is greatly weakened, and the communication lithium battery industry is in the preparation stage for adjustment. However, in the future, the demand tendency of communication lithium battery and UPS lithium battery is clear, and the enterprise is preparing for the communication energy storage market in the expansion of production.In 2021, China's energy storage lithium battery market (electric energy storage lithium battery communication energy storage lithium battery) will usher in a demand inflection point, mainly driven by policies, new infrastructure and other factors. GGII makes ten forecasts for the energy storage lithium battery industry in 2021 by combing the energy storage lithium battery industry and combining the survey data and information:Electric energy storage1. From 2019 to 2020, the new energy storage and grid connection policy was introduced. After that, the relay network side energy storage power station ushered in market space for energy storage lithium batteries.In addition, after the provinces issue the power price adjustment policy before the end of the year, it provides a better investment drive for the peak valley price difference arbitrage on the power generation side. GGII predicts that in 2021, the new energy supporting and frequency modulation market will still give priority to driving energy storage, and the user side and distributed energy storage will grow rapidly. In 2021, the demand for power energy storage lithium batteries in China will exceed 5gwh.2. Globally, more and more countries and regions are increasingly eager for fossil fuel substitutes. Renewable energy energy storage scheme is a decarbonization scheme that is agreed by all countries.Considering that governments around the world are formulating a variety of economic stimulus plans to promote economic development after the end of the epidemic, some of which will be designated for the deployment of clean energy facilities, it is expected that the global renewable energy energy storage will rebound strongly by 2021, and the energy storage lithium battery will benefit.3. As the core component of the energy storage system, lithium battery plays a vital role in the operation of the project. In participating in the bidding of domestic energy storage market, there are many enterprises in various links, which is not conducive to the division of labor in professional fields.GGII believes that lithium battery enterprises will play an important role. It is expected that more and more lithium battery enterprises will increase investment in the energy storage market in 2021. At the same time, enterprises focusing on energy storage lithium batteries will enter the production expansion stage one after another, and individual energy storage lithium battery enterprises will rush to the market and seek greater development.4. In 2021, the problems related to the safety of electric energy storage will rise to an important level. The energy storage project shall start to implement the technical standards in the whole link, such as incorporating the key constraint means such as the arrival sampling inspection of core components such as energy storage batteries, system grid connection inspection and operation assessment inspection into the process of technical supervision and inspection during and after the event.5. In 2021, the development of energy storage lithium battery will be more targeted. For example, frequency modulation energy storage will adopt products with 2C and higher magnification, so as to improve the competitiveness of enterprises.Communication energy storage1. In 2020, the transformation of 5g base stations was in full swing, and the lead-acid batteries used in the original 4G base stations ushered in a wave of "lithium for lead" replacement. GGII predicts that in 2021, the construction mode of 5g base station will start from "4G transformation" to "new 5g". The new 5g base station will bring a rapid increase in lithium battery demand. It is expected that the domestic communication lithium battery demand will reach 8gwh (excluding export) in 2021.2. In 2020, due to the impact of the epidemic, the construction of overseas base stations was less than expected. To a certain extent, it reduces the shipment of lithium batteries for domestic base stations in 2020.GGII predicts that countries after the epidemic in 2021 will start to stimulate the economy with infrastructure and vigorously develop the communication industry, especially in Southeast Asia and South Asia. It is expected that the overseas communication lithium battery market will resume high growth demand in 2021.3. In recent years, with the rapid decline in the price of communication lithium battery and the increase in domestic demand for data center, the initial large volume of UPS lithium battery has been driven. GGII predicts that the penetration rate of UPS lithium batteries in China will increase from 3% to 8% in 2021.4. In 2020, the bid winning price of base station lithium battery is as low as 0.59 yuan / wh, while the ups lithium battery pack (LFP) with conventional standby power has also been reduced to 0.73 yuan / wh. In foreign markets, under the strong competition of giants such as Panasonic and Samsung SDI, they were also forced to reduce prices, and foreign prices fell by 5-10%.Price is an important competitive factor of communication lithium battery. It is expected that the fierce price competition will continue in 2021, and the price of communication lithium battery will further decline.5. The communication lithium battery will implement modular design to improve operation efficiency and operation and maintenance efficiency. It is expected that most of the backup power supply and UPS lithium batteries of the 2021 base station will adopt modular design, and the 4850 model of lithium battery of the base station will begin to transfer to the 48100 model.
18650 Lithium Battery, Polymer Lithium Battery: Which Is Safer?
18650 Lithium Battery, Polymer Lithium Battery: Which Is Safer?
18650 lithium battery, polymer lithium battery: which is safer?It seems that the general public view is that polymer lithium batteries are safer and are said to never explode. According to my understanding, the argument that polymer lithium battery is safer mainly comes from the manufacturers of Taobao Shanzhai mobile power supply, which use polymer lithium battery as a selling point to attack products with 18650 cells.You can use "battery explosion" as the keyword. Du niangzhi, the main news related to mobile phones, but now mobile phones can't find models of non polymer lithium batteries. Therefore, the argument that polymer lithium batteries are safer than 18650 lithium batteries is untenable, and there is no argument that they will never explode. In addition to individual extreme explosion cases, bulging is almost a common problem of polymer lithium batteries.Of course, polymer lithium battery has its unique and irreplaceable advantage of 18650 (cylindrical) lithium battery: square and flat, which makes it play a big role in light and thin portable electronic devices. In addition to mobile phones, ultra-thin notebooks also use polymer lithium battery. Whether its security is high or low, as long as we can't live without the mobile phone, it's in your hand or trouser pocket.Fortunately, at present, almost all the star models of mainstream mobile phone brands use Japanese and Korean batteries, which come from large international manufacturers, and the overall safety is very high. There is no need to worry about it for daily use.Turning back to 18650 lithium battery, which is often attacked by various fake mobile power supply manufacturers. At present, it is still widely used in various electronic devices, such as mobile power supply. In fact, in high-end applications, such as professional imaging equipment and notebook batteries, 18650 has always been the main role, and the large-scale application of Tesla electric vehicles has improved the high safety image of this battery.18650 lithium battery has mature process, good consistency and high capacity density. It has irreplaceable advantages of polymer lithium battery in high-capacity hybrid applications.So, when we need to consider the type of battery in our daily life, what choice should we make? Taking mobile power as an example, my personal view is: choose products from famous battery suppliers, such as Sanyo, Panasonic, Sony, Samsung and LG, and domestic Lishen, bick, Changjiang and Zhuo Neng are also brands with certain scale and strength, with relatively high security. The safety of the cell mainly depends on the quality control of the manufacturer, not whether it is a polymer or an ordinary lithium battery.By the way, correct a widely accepted mistake: polymer lithium batteries do not mean thinner. Whether the battery is cylindrical or square, there is no significant difference in volume and weight between polymer lithium battery with the same capacity and 18650 lithium battery at the same time.The above is the personal summary of netizens' views, which does not represent the views of this site. Welcome to discuss and express your opinions.
Safety Concerns Regarding Lithium-ion Batteries
Safety Concerns Regarding Lithium-ion Batteries
Safety Concerns Regarding Lithium-ion BatteriesLithium-ion batteries have turned into an energy storage technique of choice for customer's gadgets and military and aviation space works alike. In any case, potential security risks related to the natural electrolytes that are utilized as a part of lithium-ion battery cells remain an ongoing concern. If we look at the other side, low-quality lithium-ion batteries contain high danger, dampness-sensitive electrolytes that make them inclined to unconstrained explosions. Scientists have now built up another type of flexible lithium-ion battery that is not that risky and can withstand extreme situations including submission and ballistic effect.The present generation of batteries indicates impressive potential, but they are still in the prototype phase. The scientists want to expand the robustness of the electrolyte and the energy thickness of the batteries significantly further. According to one of the scientists named Gerasopoulos, this work. However, it also demonstrates the idea that they can construct safe lithium-ion batteries that can survive mechanical abuse.Li-ion Battery Manufacturers are now providing batteries and cells that are more of an indispensable power source for multiplying devices for example, Li-ion cell for inverter bulb. Also, many Li-ion batteries are known to catch fire on an occasional basis and to understand the knowledge with what went wrong when batteries fail and how to address the security risk, researchers stated that they have discovered a potential method to rack lithium-ion as they go in a battery.To make these batteries protective and secure, BMS i.e. Battery Management System also plays an important role. It makes sure that battery wo not get overcharged or over discharged but creating a balance. At a point when a gadget is at charging, achieves the highest voltage, BMS will subsequently control it by indicating that it should not chare further for a protective impact. Similarly, when a battery will go at its lowest, BMS will shut down the output voltage and the battery can not keep on discharge long last, the gadget will power off as well. If we tell you as a whole, then BMS is the best system supplier for any battery.Many of the present electronic systems are going down solely from sunlight based power and batteries. And, talking about the benefits, it's always better than choosing a lithium-ion over lead-acid batteries anyway. Lifepo4 batteries (Lifepo4 Battery Manufacturer) have a suture 10 times longer than the other traditional ones. It also significantly decreases the necessity for battery changes. Lithium press phosphate batteries work with much lower insurance and consequently restore at a speedier rate, also, they are lighter in weight than the other lead destructive batteries, to be more specific, around 1/4 less. LifePO4 gives twofold as far as possible in a similar measure of room. All in all, Lithium batteries are also environmentally friendly and safer to use in any sort of gadget.Originally published at mora-mmbo.weebly.com— — — — — —Best 200Ah Lithium Battery: What Your Trip Needs | Caravan & Camping ProductsBest 200Ah Lithium Battery: What Your Trip Needs Lithium batteries are becoming the go-to power source for caravans in Australia. Especially a 200Ah lithium battery. It's easy to see why! Lithium batteries are not only lightweight. They also boast a high performance and have an incredible life cycle compared to other battery types. A lithium battery might look similar to a lead acid AGM battery. But the way they work is very different. The charge and recharge process for an AGM battery uses a chemical reaction. A lithium battery uses ions. For a caravan or RV, the big advantage of lithium batteries is their size and weight. A lithium caravan battery not only takes up a much smaller footprint, but is half the weight of a traditional lead acid battery! Pro tip: Swapping out your old AGM battery for a lithium can ensure your RV does not go over the legal weight limits. Another huge benefit is that a lithium caravan battery provides 60% more usable power than its counterpart! This is because it has a depth of discharge of 80% compared to 50% for an AGM battery. Plus, a lithium battery will give you almost double the lifecycle of the AGM equivalent. The 200Ah lithium battery is the most popular size for caravans and 4WDs. A 200Ah lithium battery gives you everything you need to run high current appliances and gadgets on a longer road trip, with all the benefits of weight, size and efficiency.

Best 18650 Batteries and Chargers - Equivalents and Replacements
Best 18650 Batteries and Chargers - Equivalents and Replacements
Best 18650 Batteries and Chargers - Equivalents and ReplacementsBest 18650 Batteries and Chargers - Equivalents and Replacements Rechargeable lithium ion 18650 batteries are common power source choice for many electric and electronic devices often found on small and large fishing or leisure boats and even kayaks. Since their characteristics degrade over time, they must be occasionally replaced - and choosing right replacement can be a nightmare, but it should not be. Also, after replacing with new batteries, old batteries should be recycled. 18650 batteries are commonly found in diving, tactical, EDC and other flashlights, in battery packs powering cordless electric tools, marine electronics, trolling motors etc. Before buying new 18650 batteries, there are many things to consider. Dimensions - official physical dimensions of 18650 rechargeable batteries are (diameter x length) 18.6 × 65.2 mm (0.73 x 2.56 inches). When these values are rounded, they are 18 mm diameter, 65 mm length, hence the name '18650' battery. But, these dimensions differ slightly from model to model, but in most situations, these small variations are not so important. Other very similar batteries are: - 16650 battery - same length, but slightly narrower batteries. Some devices accept both 16650 and 18650 batteries, just be aware that 16650 batteries often have lower capacity and come unprotected (no protective electronics in the battery), - 19670 battery - slightly larger battery than 18650 battery. 19670 batteries commonly come with protective electronics (protect the battery from short circuit, overcharging, prevent overheating and similar), and are known as 'protected 18650 batteries'. But there are also unprotected 19650 batteries, often offering really large capacities, especially when compared with high-drain, protected 18650 batteries. - CR123A battery - this is primary (non-rechargeable) 3 V lithium battery, 17 mm diameter, 34.5 mm in length. Some devices accept both 18650 battery or two CR123A batteries for one 18650 battery. Main advantage of CR123A batteries is their extra long shelf life - up to or even more than 10 years. For example, some EDC flashlights for occasional use recommend CR123A batteries and for regular use they recommend 18650 batteries. Of course, there are also rechargeable CR123A batteries, offering 3.6-3.7 V per cell, slightly smaller capacity than primary CR123A - such batteries are often designated as 16340 batteries. - 17670 battery has twice the length of standard CR123A battery and often can be used instead of 18650 (if additional 2 mm are not problem). Note: having an option to replace 18650 battery with another battery sounds great, but the best replacement battery for 18650 battery is another 18650 battery :) Protected battery - protected lithium ion batteries come with a protective electronic circuitry which monitors parameters of the battery and protect the battery from overcharging, over-discharging, high charging/discharging currents, prevent overheating etc. Since lithium ion batteries pack lot of energy in small packages, having protective circuitry is recommended. On the other hand, this circuitry decreases capacity of the battery. IMHO, for small devices like flashlights and similar, where current drain is rarely above 1-2 Amps, protective electronics in batteries is overkill, especially since many modern flashlights already comes with smart electronic controllers which also monitor the status of the battery. Button or flat type - some models come with button top side (positive), while some batteries come with flat top side. Before purchasing new 18650 batteries, be sure to check your old batteries - most devices and chargers accept both models, but better safe than sorry. Photo above batteries - on the right is positive (top) side of 'flat top' battery and on the left side is positive (top) side of 'button top' battery. Soldering tabs or not? When building a battery pack, soldering tabs help significantly. However, be very careful when building custom 18650 battery pack - be sure that all of the batteries come from the same manufacturer, that they are of the same model and preferably the same batch. Connecting in parallel or in series - connecting lithium ion batteries in parallel can be done using special circuitry. Reason is that even the slightest variations in capacity and chemistry can lead to over-discharging or overcharging some cells, which can lead to overheating and possible fire hazard. Connecting lithium batteries in series is relatively safe, when protected cells from the same manufacturer are used. When individual cell is, for example over-discharged, it will shut off and whole pack will stop to provide energy. If more such packs are connected in parallel, this can lead to over-stressing remaining 'sub-packs'. When connecting 18650 batteries in series, they provide: High capacity vs. high current 18650 batteries - some batteries are optimized for capacity, some batteries are optimized for high discharge currents. High capacity 18650 batteries come with stated capacities of 5000 or even 6000 mAh, but their continuous discharge currents are rarely larger than, for example, 10 Amps. Some batteries can safely provide 30 A, continuously, but such batteries rarely have capacity of more than 2000-2500 mAh. Newer lithium ion manganese oxide batteries improve maximum stated continuous currents, while having would ecent' capacity. Choosing the right battery depends on your application - if it is flashlight or electronic device, requiring just few Amps, go for high capacity models. For high power devices, go for high current batteries. Note: if you need lightweight fishfinder or even trolling lithium battery, consider purchasing finished lithium battery pack - some manufacturers even offer lithium packs with built-in protective circuitry allowing such packs to be charged using lead-acid battery chargers. On the other hand, such battery packs cost much more than lead-acid fishfinder or trolling motor batteries. However, there are many companies that buy finished cells and wrap them with their own markings. Such wrapped batteries can come from reputable manufacturers and can be quite good batteries, but there are also cheep knockouts which are simply not good. And NOT safe. So, when buying 18650 batteries, be sure to get batteries from reputable sellers/manufacturers and the batteries with good reviews. Note: Amazon affiliate links in the table open in the new windows. Although there are many other 18650 batteries on the market (with higher claimed capacities, very low self-discharge rates, high dicharge currents), if you need general, sturdy and tough battery, go for Samsung 25R - it is very popular battery with good maximum current and would ecent' capacity. We say would ecent', but this battery can withstand many charge/discharge cycles, it is reliable and is very often used as a 'standard battery' for evaluating other batteries. Also, LG HG2 is very good battery with nice balance between capacity and maximum continous current. If you need good and reliable, high capacity battery, go for Panasonic NCR18650B 3400 mAh battery. There are 18650 batteries on the market with larger capacity, even with good reviews, but . Last thing than a fishermen or outdoor enthusiasts need is failed equipment because of the cheap, unreliable batteries. Never go cheap with batteries and similar equipment - one day, your life can depend on it. Note: author of this article has Masters degree in electronics and he still uses dual purpose AGM lead acid battery as the main boat battery and he does NOT plan on moving to lithium ion batteries as the main boat battery any time soon - actually, probably not for next few decades. However, his main flashlights are powered via rechargeable 18650 batteries AND non-rechargeable CR123A (with few new CR123A as spare batteries), just to be sure :) What Does IMR, IFR, ICR, INR Stand For? Often, one can see letters IMR, IFR and ICR as part of battery labels. - IMR batteries are based on LiMn 0 (Lithium Manganese Oxide) chemistry, their nominal voltage is 3.6 - 3.7 V, maximum recommended charging voltage is 4.2 V. IMR batteries commonly have smaller capacity, but are capable of delivering stronger currents. - IFR batteries are based on LiFePO (Lithium Iron Phosphate) chemistry, their nominal voltage is 3.2 - 3.3 V per cell, maximum recommended charging voltage is 3.5 - 3.6 V. - ICR batteries are based on LiCoO (Lithium Cobalt Oxide) chemistry, their nominal voltage is 3.6 - 3.7 V, with maximum recommended charging voltage 4.2 V. They commonly have higher capacities, but maximum allowed currents are limited to just few C, if even that. - INR batteries are based on LiNiMnCoO (Lithium Manganese Nickel) chemistry. Very similar to IMR batteries, they can provide plenty of currents, with slightly lower capacity. Note: unprotected ICR batteries vent out easily, but other chemistry batteries must be treated with respect, too. Also, there are other technologies, including hybrid technologies like: Lithium Nickel Cobalt Oxide (LiNiCoO ), Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO ), etc. When buying good 18650 battery charger, there are few things to consider, like: - charging of all 18650 battery types, regardless of their chemistry, - optional charging of other batteries, not just 18650 batteries, - charging of different batteries at the same time, etc. Big brands like Sony, LG, Samsung and Panasonic have very good chargers, but there also chargers from other companies that perform exceptionally well. Following table lists some of the most popular, high quality, 18650 battery chargers (alphabetic order): Note: Amazon affiliate links in the table open in the new window. Obviously, there are many more 18650 battery chargers, but these chargers are very popular for their features and are often considered 'the best' on the market. But which one is really 'the best'? Well, it depends on many things, but IMHO, if you are not 100% sure, be sure to check NiteCore DigiCharger D4 Amazon link.

Salvaging Rechargeables for Projects : 6 Steps (with
lithium polymer and lithium ion batteries aren't extremely expensive but if you use them in a lot of your projects it can run up quite a big bill. So in this Instructable we are going to take a look at the different places you can find them for cheap or often free and how to make sure the ones we find are reliably able to hold a charge and are most importantly safe to use.luckily taking apart cells and checking them isn't the hardest thing in the world to do but there are some tools that make it a lot easier and less time consuming these are:Lithium is the most common type of rechargable battery used in consumer electronics, there are two types of lithium batteries that are used, these are lithium ion and lithium polymer, don't get these confused with no-rechargeable batteries like 9 volt, AA, AAA and some coin cells which are all made of alkaline if you attempted to charge these you'd not have a fun time. Tones of electronic devices use these batteries but the cheapest places to find them is in old laptops. If you go to ewaist facility and ask them for laptop batteries you can get them for reeeeeally cheap while you're there you might as well keep and eye out for anyother electronics that look like they might have a battery inside such asWhile finding these other battery sources is easy i would defiantly recommend sticking to only looking for laptop batteries and they are the cheapest, have the highest quality brands, and the most cells within the battery.laptops typically use 12 volts as an operating voltage but a lithium cell can only provide and average of 3.7 volts meaning that most laptop manufactures arrange 3 batteries in series which creates one battery with a total voltage of 11.1 volts. But most laptops have 6 cells (for a longer run time) and still have a voltage of 11.1 volts. This is because the cells are divided into couples of 3, these couples are connected in parallel which keeps the voltages at 3.7 volts then the 3 couples are connected together in series to get a voltage of 11.1 volts. Anyway now that we know how they works lets get them out, most older laptops use a lithium ion cell called 18650 which is a very common battery type, some of the Tesla cars actually run on these batteries! The 18650 cells have a metal cylinder shape, they are pretty easy to get out of the battery case all you have to do is pull the casing apart and cut all the cables you can see, you'll see that all the cell are connected together with a thick flat metal connector, we need to slowly and carefully pull this off the battery taking care not to let any pieces of metal touch, if the metal refuses to peel off stop pulling and just cut the metal once this is done you should have a nice collection of batteries, just a heads up most newer and thinner laptops doesn't use 18650 cells because they are too thick so they use a lithium polymer cell if you find these you can use them in the same way as you would use the 18650 just be a bit more careful with them as they don't have any protection around them so its pretty easy to puncture them and cause an internal short circuit.So now we've got the cells out of their casing and seperated them, this is where we are going to need a multimeter, over time some cells degrade, leak or rust which will result in a dead cell. Finding cells that have leaked or rusted are pretty easy just keep an eye out for discussing oozing batteries or rust however finding degraded cells isnt that easy, a cell may look perfectly healthy but is just completely dead, these are the degraded cells we find them by hooking them up to a multimeter and then put it on voltage mode, the positive probe goes to the postive terminal of the cell and the negative probe goes to the negative terminal. If the voltage is bellow 2.5 volts it means its kind of degraded but can still hold a charge, we are going to want to avoid them if possible however anything bellow 1 volt is completely dead and should be deposed of at a battery recycling facility. The ideal voltage you are looking for is between 3 and 4.2 Volts Now we should end up with a group of cell that have a voltage between 3 and 4.2 volts but this doesnt mean its completly healthy as the cells may loose charge over time at a fast rate, to make sure this isnt happening charge the cells up to 4.2 volts, this can be done with a lithium charger the one im using has over charge protection meaning it will stop charging the cell when it gets to 4.2 volts which is really nice, once they are charged all the way to 4.2 volts leave them somewhere safe and check the voltage every couple of hours for a few days if the voltage drops significantly it means the cells cannot hold a charge and shouldnt be used. One of the cells I was testing started at 4.1 volts and dropped all the way to 3.6 volts over 2 days which was very bad.Lo and behold we should now have a bunch of working lithium cells that can now be used for our projects! if you want to see a project where i used one of these salvaged cells to power a led photography and video light check out this instructable: the cell that rusted, leaked, degraded or could hold a charge should not just be thrown in the trash, they need to be taken to a battery recycling facility and deposed of properly .Thanks so much for reading, if anything wasn't clear please feel for to leave a comment or send me a message and ill try my best to get back to you!
Exceptional Long-life Performance of Lithium-ion Batteries Using Ionic Liquid-based Electrolytes
Exceptional Long-life Performance of Lithium-ion Batteries Using Ionic Liquid-based Electrolytes
Exceptional long-life performance of lithium-ion batteries using ionic liquid-based electrolytesAdvanced ionic liquid-based electrolytes are herein characterized for application in high performance lithium-ion batteries. The electrolytes based on either N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (Pyr TFSI), N-butyl-N-methylpyrrolidinium bis(fluoro-sulfonyl)imide (Pyr FSI), N-methoxy-ethyl-N-methylpyrrolidinium bis(trifluoromethane-sulfonyl)imide (Pyr TFSI) or N-N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium bis(trifluoromethanesulfonyl)imide (DEMETFSI) ionic liquids and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt are fully characterized in terms of ionic conductivity, viscosity, electrochemical properties and lithium-interphase stability. All IL-based electrolytes reveal suitable characteristics for application in batteries. Lithium half-cells, employing a LiFePO polyanionic cathode, show remarkable performance. In particular, relevant efficiency and rate-capability are observed for the Py FSI-LiTFSI electrolyte, which is further characterized for application in a lithium-ion battery composed of the alloying Sn-C nanocomposite anode and LiFePO cathode. The IL-based full-cell delivers a maximum reversible capacity of about 160 mA h g (versus cathode weight) at a working voltage of about 3 V, corresponding to an estimated practical energy of about 160 W h kg . The cell evidences outstanding electrochemical cycle life, i.e., extended over 2000 cycles without signs of decay, and satisfactory rate capability. This performance together with the high safety provided by the IL-electrolyte, olivine-structure cathode and Li-alloying anode, makes this cell chemistry well suited for application in new-generation electric and electronic devices.— — — — — —What revolution is made by using the lithium-ion batteries?Small size battery:nAll the drones we see in market are powered by li ion , mobile are more lighter than ever before , e bike, e cycle ,wearable electronics products .nHigh capacity Li-ion batteries(Lithium Ion Battery Cells)Large size battery :nThe revolution is coming with large capacity battery which we replace the conventional method for using electricity . Tesla PowerwallWhat revolution is made by using the lithium-ion batteries?.— — — — — —How long can lithium ion batteries hold their charge?Each of the six Li-ion chemistries will have a different self-discharge rate. LFP is used in China for EVs, and it holds its charge pretty well. For example, I have 80Ah LFP cells in my garage in storage for over 5u2013years, and their voltage dropped from 3. 5 to 3. 2V. The garage is not heated or cooled. The year-round temperature is in the 20u201390F range (-22 to 32C). Cell phone battery is usually LCO, so it might have a higher self-discharge rate, which is why you should always keep your cell phone and laptop plugged in as often as possible— — — — — —Olivine-Type Cathode Materials for Lithium-Ion BatteriesLithium-ion batteries (LIBs) have been widely adopted as the most promising portable energy source in electronic devices because of their high working voltage, high energy density, and good cyclic performance. Currently, LIBs are used in electric vehicles and hybrid electric vehicles as well. In these batteries, olivine-type cathode materials such as LiMPO (M=Fe and Mn) have attracted significant interest, especially due to their low cost and high intrinsic safety. However, they show poor electrochemical properties mainly due to their low electrical conductivities. Thus far, a number of attempts have been made to enhance the electrochemical properties of olivine-type cathode materials, including particle-size reduction,1 cation doping,2 carbon coating of LiMnPO ,3 and use of LiMnPO /carbon composite.2,4 Several synthesis routes have been developed to overcome the weakness of LiMnPO4 3 such as solid-state reaction,4-6 sol-gel method,2,3 polyol process,7 hydrothermal synthesis8 precipitation,9 and electrostatic spray deposition.10 However, the electrochemical performance of LiMPO cathodes prepared using the aforementioned techniques does not yet meet the application needs of commercial cells. Spray pyrolysis (SP) is a well-known continuous and single-step method for the preparation of fine homogeneous high-purity multicomponent powders. Compared to particles prepared by soft chemistry methods, SP yields a narrow particle size distribution that can be controlled from the micrometer to sub-micrometer scale. Moreover, SP can be used to achieve highly pure powders with easily controllable composition. About a decade ago we first reported that the spherical nanostructured LiMn O and its substituted forms could be prepared by spray pyrolysis.11,12 Recently, we have also reported that LiMPO /C (M=Fe, Mn, Co) nanocomposites13-16 with excellent electrochemical properties can be successfully synthesized using a combination of SP, ball milling, and heat treatment. Some of our recent results on LiMPO /C composites are summarized in this article. Synthesis and Electrochemical Properties of LiFePO /C Nanocomposites LiFePO /C nanocomposites were prepared at 500 °C by SP and then wetball milled (WBM) at a rotating speed of 800 rpm. The WBM with ethanol was performed for 3 h in an Ar atmosphere, and the milled mixture was heat-treated at 600 °C for 4 h in a N 3% H atmosphere. Transmission electron microscopy (TEM) revealed that the LiFePO nanoparticles, with a geometric mean diameter of 146 nm, were coated with a thin carbon layer of several nanometers (Figure 1). The first charge-discharge profiles of cells containing carbon-coated LiFePO nanoparticles with increasing charge-discharge rate from 0.1 to 60 C between 2.5 and 4.3 V are presented in Figure 2. At a charge-discharge rate of 0.1 C, the cell has a discharge capacity of 165 mAh g-1, which corresponds to 96% of the theoretical capacity of LiFePO (170 mAh g-1) and a much smaller polarization loss and irreversible capacity. A wide flat voltage plateau corresponding to the Fe2/Fe3 redox reaction is observed at 3.4 V. The first discharge capacities at charge-discharge rates of 1, 5, 10, and 20 C are 155, 130, 118, and 105 mAhg-1, respectively. Even at a rate of 60 C, the electrode containing carbon-coated LiFePO nanoparticles has a discharge capacity of 75 mAh g-1. The cyclic performance of the cells containing carbon-coated LiFePO nanoparticles at different charge-discharge rates was investigated over 100 cycles, and the results are given in Figure 3. The cells exhibit an excellent cyclic property. The cells show no capacity fading even after 100 cycles at different charge-discharge rates ranging from 1 to 60 C. These results demonstrate that the structure of the carbon-coated LiFePO nanoparticles is very stable, and the electrochemical lithium-ion insertion/extraction process is quite reversible even at high chargedischarge rates. These results indicate that the preparation approach using the combination of SP and WBE followed by heat treatment enables to achieve a high rate performance for LiFePO composite electrode materials. Synthesis and Electrochemical Properties of LiMnPO /C Nanocomposites LiMnPO /C nanocomposites were prepared using a combination of SP, WBM and heat treatment. The SP was performed at 300 °C, whereas the heat treatment was performed at 500 °C for 4 h in a N 3% H atmosphere. X-ray diffraction (XRD) was used to confirm the ordered LiMnPO olivine structure without any impurity phases. The scanning electron microscopy (SEM) and TEM also confirmed that the final sample was the LiMnPO /C nanocomposite with a primary particle size of 100 nm. The TEM of the final sample is shown in Figure 4. Both phases of carbon and LiMnPO could be seen in this image. Figure 6 shows the rate capabilities determined for three charging modes: (1) CC charge up to 4.4 V, (2) CC charge up to 4.8 V, and (3) CC charge up to 4.4 V followed by CV charge reaching to theoretical capacity for LiMnPO /C nanocomposite containing cell. At the discharge rate of 0.05 C, the cell exhibits the first discharge capacity of 123, 153, and 147 mAh g-1 in CC-4.4 V, CC-4.8 V and CC-CV modes, respectively. At a discharge rate of 1 C, the initial discharge capacity of 51, 107, and 123 mAh g-1 were observed for CC-4.4 V, CC-4.8 V and CC-CV modes, respectively. Even with a discharge rate of 10 C, the cell could deliver capacity of 65 mAh g-1 in CC-CV mode. In spite of the intrinsic low electronic and ionic conductivities of LiMnPO , the cells containing LiMnPO /C nanocomposites exhibit very good rate capability, which could be attributed to the large specific surface area, the small primary particle size, and a uniform carbon distribution. Synthesis and Electrochemical Properties of LiCoPO /C Nanocomposites LiCoPO4/C nanocomposite also was successfully prepared by using a combination of SP and WBM followed by heat treatment. The SP was performed at 300 °C, whereas the heat treatment was performed at 500 °C for 4 h in a N 3% H atmosphere. The XRD analysis confirms that the LiCoPO /C nanocomposite is well crystallized in an orthorhombic structure with Pmna space group. SEM and TEM equipped with energy dispersive spectroscopy technique reveals that the LiCoPO /C nanocomposites are agglomerates of LiCoPO primary particles with a geometric mean diameter of 87 nm, and the carbon is well distributed on the surface of the agglomerates. Figure 8 presents the first discharge profile of the cells containing LiCoPO /C nanocomposites as active cathode materials at 0.1 C. For comparison, the discharge profile of cells containing LiCoPO is also shown in the same figure. The LiCoPO /C nanocomposite cathode exhibits a wide and flat voltage plateau around 4.75 V. It can be noted that in comparison to LiCoPO , the LiCoPO /C nanocomposite cathode delivers a larger discharge capacity (94 mAh g-1 for LiCoPO vs. 141 mAh g-1 LiCoPO /C nanocomposite). Figure 9 shows the rate capabilities of the cells containing LiCoPO and LiCoPO /C nanocomposites. The cells containing LiCoPO4 exhibit first discharge capacities of 99, 94, 78, 53, and 11 mAh g-1 at 0.05, 0.1, 1, 5, and 20 C, respectively; the cell containing LiCoPO /C nanocomposites shows first discharge capacities of 142, 141, 137, 128, and 109 mAh g-1 at 0.05. 0.1, 1, 5, and 20 C, respectively.

Yiwei Lithium Energy Capital Channel Changing "filling" Cylindrical Ternary Battery
abstractAccording to the announcement of Yiwei lithium energy, the raised funds for the "high-performance lithium-ion power battery industrialization project" will be changed to the "high-performance lithium-ion cylindrical battery industrialization project" implemented by Jingmen Chuang energy, a wholly-owned subsidiary.The market demand for lithium batteries for electric tools is booming, and Yiwei lithium energy funds change channels to "fill" cylindrical ternary batteries.According to the announcement of Yiwei lithium energy, the raised funds for the "high-performance lithium-ion power battery industrialization project" will be changed to the "high-performance lithium-ion cylindrical battery industrialization project" implemented by Jingmen Chuang energy, a wholly-owned subsidiary.This move is intended to further obtain the recognition of high-quality customers in the power tool market, expand business cooperation opportunities with international well-known power tool giants, reduce product costs through large-scale production, and further improve the market share of cylindrical ternary lithium-ion battery.According to the announcement, "high performance lithium ion cylindrical battery industrialization project" is mainly for the supporting application of electric tools. The project plans to invest 3.03 billion yuan, and the fund-raising investment for this change is 600 million yuan.In fact, this is not the first time Yiwei lithium has implemented change fund-raising investment for the project. In November 2020, Yiwei lithium energy has used 300 million yuan of the raised funds of "Jingmen Weichuang energy storage power lithium ion battery project" for the establishment of cylindrical battery production line for electric tools.Two capital transfers in just six months are enough to see the prosperity of the demand for lithium batteries for electric tools.Yiwei lithium energy said that the company's ternary cylindrical battery products have been widely recognized by customers at home and abroad. The company's existing site and production line have been operating at full capacity, but the supply still exceeds the demand in recent year.Gaogong lithium battery noted that since Q2 of 2020, domestic power tool battery enterprises have rapidly recovered and entered full production. Then, in Q3 and Q4, insufficient production capacity has become the biggest "trouble" for these enterprises.The reason behind this is that, on the one hand, many international power tool enterprises such as TTI, Sb & D and Bosch have shifted the focus of their industrial chain to China. Local manufacturing and localized procurement strategies directly promote the domestic power tool lithium battery industry to accelerate the industrial transformation and layout.On the other hand, since 2020, Japanese and Korean enterprises have obviously shifted their focus to the field of power batteries. The release of large-scale market gap also allows Chinese enterprises with comprehensive advantages such as performance, scale and cost to seize greater market opportunities.As an important battery supplier of TTI, Yiwei lithium energy has also greatly reduced the supply of its cylindrical ternary battery in the two wheeled vehicle market to vigorously meet the market demand of electric tools.GGII analysis believes that the substantial growth of domestic electric tool batteries is not a short-term behavior under the epidemic, but will be the next normal and general trend. With the accelerated penetration of Chinese lithium battery enterprises in the international electric tool market, it is expected that by 2025, the shipment of electric tools in China will reach 15gwh, with an annual compound growth rate of more than 22%.It is worth mentioning that in addition to Yiwei lithium energy, haisida, blue lithium core, Penghui energy and Changhong new energy are also expanding the production of cylindrical batteries for electric tools.Editing: JQ
Safety Precautions and Disposal Methods of Polymer Batteries
Safety Precautions and Disposal Methods of Polymer Batteries
The lithium polymer battery is a new, rechargeable lithium-based battery. Lithium polymer was developed as a lower cost and a more stable version of the lithium-ion cell. But there are certain safety measures that need to be followed when using such polymer batteries. They are also known as lipo cells.SAFETY PRECAUTIONS:• Never allow Lithium battery to be charged or discharged on or near combustible materials, this includes paper, plastic, vinyl, carpets, leather, wood, inside an R/C model or full-sized automobile.• Do not put packs in the pocket of any clothing.• Never allow lithium batteries to come in contact with moisture or water at any time.• Never store the batteries near an open flame or heater.• Never assemble Lithium batteries or pre-assembled packs together with other Lithium cells/packs. Only a qualified battery assembly company should assemble or modify LiPo batteries.• Do not allow LiPo cells to become punctured, especially by metallic objects such as screwdrivers, T-pins, or hobby knives.• Always provide adequate ventilation around LiPo batteries during charge, discharge, and during storage. If a battery becomes overheated immediately place it in a fire-proof location until it cools.• Always store LiPo cells/packs in a secure location away from children.• ALWAYS make sure that metallic objects, such as wristwatches, bracelets, or rings are removed from your hands when handling lithium polymer battery. Accidentally touching battery terminals to any such objects could create a short-circuit condition and possibly cause severe personal injury.Besides the safety measures the disposal of the lithium batteries also need to be disposed properly. Lithium-polymer batteries are environmentally friendly, still, there are some things that need to be kept in mind.• For safety reasons Lithium batteries should be fully discharged before disposal (however, if physically damaged it is NOT recommended to discharge LiPo cells before disposal - see below for details). The batteries must also be cool before proceeding with disposal instructions.To dispose the LiPo cells and packs:1. Place the LiPo battery in a fire-proof container or bucket of sand.2. If any LiPo cell in the pack has been physically damaged, resulting in a swollen cell or a split or tear in a cell's foil covering, do NOT discharge the battery.3. Connect the battery to a LiPo discharger. Set the discharge cutoff voltage to the lowest possible value, and the current as low as 20mA if possible. It's also possible to discharge the battery by connecting it to an ESC/motor system and allowing the motor to run indefinitely until no power remains to further cause the system to function.4. Discharge the battery until its voltage reaches 1.0V per cell or lower.
Battery, Lithium and Other Heavy Metal Innovations
Battery, Lithium and Other Heavy Metal Innovations
Battery, Lithium and other Heavy Metal InnovationsBy Michele the TrainerBattery innovations and improving batteries is important for storing energy and our sustainable future. Cars, phones and laptops have become essential but these all require batteries. Many of us love these technical marvels but love planet earth too. Our sustainable future depends on renewable energy and battery innovation. Recycling both our batteries and raw earth elements is imperative.Loud noise is an attention-getter.Remember when Metallica did Battery?Remember when Nirvana did Lithium?Now that the soundtrack for our story has been established, let's talk real heavy metals. I want to draw your attention to the earth's cost for our cool tech. We love these inventions, but we must still give attention to solutions that will be sustainable and decrease the cost on our planet or the future.Our world needs upgrades, such as longer lasting batteries (or more charging cycles per battery), so we can move away from fossil fuels. We need electric vehicles (EV). Embrace the tech. Please do not avoid EV due to batteries. Self-driving renewable energy cars will happen. Solutions and progress will happen!Metals used in batteries are more than we would think. At a minimum, we've heard of lithium, nickel, cobalt and aluminum oxide. Today most lithium is in China. "China controls about 95 percent of the global market for rare earth metals and expects to use most of these resources for its own production."Tesla's Elon Musk is leading the charge on battery innovation, recently announced that he might want to consider mineral mining. One can speculate that this is partially due to today's issues surrounding trade, and ability to get the materials needed to continue the innovation our world needs. Today we have one lithium mine in the USA.Any environmentalist will agree that more mining is not an ideal solution. We need other ideas.Safety and Recycling Batteries:Nobody likes the risk of fire. We've all learned a lot about battery hazards due to certain cell phone recalls. Further, today's lithium batteries can be risky due to inherent shorting issues, and we all need safer options.Do not just throw lithium batteries into the bin. Often it actually illegal to throw lithium ion batteries in the trash. They must be disposed of properly because reintroducing some of the elements can be hazardous. Call your local hazardous waste program and ask them about how to properly discard, donate or recycle your batteries. Attention to New Ideas:Less mining, less waste and less hazard is necessary for our energy storage needs and sustainable renewable energy future. Here are two gems I've found in the new idea space:Glass batteries that "keep getting better" with age including increased charging cycles: A Glass Battery That Keeps Getting Better?Bill Joy from Sun Microsystems has an interesting idea that has been prototyped. A bigger large-scale solid-state solution that support our entire energy grid (not just a power grid). While the trade issues are headlining with mining and more mining, we must keep our eyes on innovation, upgrades and recycling because improving the tech of energy storage is a better solution than increasing mining. Improvements for recycling today's battery waste are awesome too.Make your own loud noise. I am interested in hearing about other innovations you might know about. Give a loud rock star round of applause to Joy and Musk and other leaders that are thinking this forward. Together let's use our devices to keep our ears, eyes and attention on creative innovation and solutions for our energy storage.︵‿︵‿︵‿︵‿︵ ‿︵‿︵‿︵‿︵‿︵‿︵Like what I do?
