Lithium-ion battery are fire hazards, so How should we store the lithium batteries?
You can find more information on our web, so please take a look.
In general, Lithium ion batteries (Li-ion) should not be stored for longer periods of time, either uncharged or fully charged. The best storage method, as determined by extensive experimentation, is to store them at a low temperature, not below 0°C, at 40% to 50% capacity. Storage at 5°C to 15°C is optimal. Since lithium batteries self-discharge, it is recommended that they must be recharged every 12 months.
We can further divide it into short-term storage and long-term storage.
Short-term storage: Store the battery in a dry place with no corrosive gases and a wet temperature between -20&#;-35&#;, higher or lower temperature will cause the metal parts of the battery to rust or the battery to leak.
Long-term storage: As long-term storage will cause the battery activity passivation and accelerate the self-discharge rate, the ambient temperature should preferably be between 10&#;-30&#;, in addition, it is necessary to do a charge/discharge cycle every 3 months to maintain its activity and recovery performance.
Charge 40% to 50% of the battery charge, and refrigerate in a dry environment. Cooler temperatures and less charge is conducive to maintaining the life of the battery, but too little charge can not be, because the battery will be self-discharge in storage, once the battery slowly run out of power, it will seriously shorten the battery life.
The extent of the effect can be referred to the following relationship between the storage temperature of lithium batteries and the rate of permanent loss of capacity.

FAQ about lithium battery storage
For lithium-ion batteries, studies have shown that it is possible to lose 3 to 5 percent of charge per month, and that self-discharge is temperature and battery performance and its design dependent. In general, self-discharge is higher as the temperature increases.
A fully discharged battery is understood to be &#;squeezed out&#; until it doesn&#;t produce any more of this current at all. In this case, the voltage drops to 0 volts. If this state is maintained, the electrodes in the battery will chemically react, rendering it partially to completely unusable. The result is that the capacity of the battery is greatly reduced and may not be recharged. Therefore, the battery should not be discharged below the final cut-off voltage associated with the type and should be recharged as soon as possible. Therefore, lithium-ion and lithium-polymer batteries should essentially not be discharged to the point of being completely unusable.
As a rule of thumb, lithium-ion or lithium-polymer battery packs are recommended to be charged at about 10 to 20 percent of remaining capacity. Good lithium ion rechargeable batteries generally have extensive protection and/or monitoring circuitry within the battery pack to prevent full discharge/overcharge and explosion.
3. in what temperature range should the lithium battery be used?
Lithium-ion batteries can be used in a temperature range of -20°C to +55°C.However, charging can usually only take place at temperatures of +0°C to +45°C.
4. How long is the battery life?
Lithium-ion batteries can be charged up to 1,000 times (depending on capacity). However, these values can only be achieved under optimal conditions. Depending on the handling and maintenance of the battery, the number of cycles may be reduced. During the service life, the capacity will decrease. Generally speaking, when the nominal capacity of the battery is less than 70%, it is called worn-out.
5. What is the memory effect (using NiCd technology) and/or the lazy battery effect?
The battery keeps track of its intensity of use. If the battery is not fully discharged before charging, small crystals will form on the electrodes and they will be less likely to accept an electrical charge. Thus, if the battery is not fully discharged one at a time, the operating time of the battery becomes shorter and shorter.
In the case of NiMH technology, a battery inertia effect (lazy battery effect) comparable to the classical memory effect occurs. Lithium-ion and lithium-ion polymer batteries can and may be recharged at any time. These batteries do not have a memory effect and should only be recharged at frequent short intervals. In addition, full charging in several stages, with or without partial discharge in between, will not cause any damage.
However, lithium-ion and lithium-ion polymer batteries should not be fully discharged.
According to the experiment, if there is about 10% to 20% of the remaining capacity of the lithium ion polymer battery, charge it. Note that disconnecting a fully charged battery pack and reconnecting it to the charging unit will not result in a higher charge. This procedure will impair the performance capability of the battery.

Li-ion battery technology uses lithium metal ions as a key component of its electrochemistry.
Lithium metal ions have become a popular choice for batteries due to their high energy density and low weight. One notable example is lithium-ion batteries, which are used in a wide range of electronic devices, from smartphones to laptops. Another type, lithium iron phosphate batteries, offer greater stability and a longer lifespan. This makes them well-suited for use in electric vehicles and large-scale energy storage systems.
Basically, lithium batteries have four key components.
What are the Different Applications and Uses of Lithium Ion Batteries?
Li-ion batteries have many applications in the real world aside from simply running the apps you&#;ve downloaded onto your smartphone. Here are just a few of them.
Rechargeable lithium batteries have become common in pacemakers because they provide long life, low drain current, high energy density, and desirable voltage characteristics. Pacemaker Li-ion batteries have a typical lifespan of seven to eight years and often weigh less than 30 grams. Primary lithium cells experience a 10% loss of capacity over five years.
For a digital camera to function effectively, it requires a robust and high-energy-density power source. So most mirrorless cameras and DSLRs take advantage of the many benefits of using lithium-ion batteries as a power source.
These rechargeable Li-ion battery packs are much smaller than other battery types and, generally, have a much larger power capacity and superior battery performance.
Many camera brands stay loyal to a specific Li-ion battery design throughout many generations of cameras. This means that even when users upgrade their digital camera, they can use the same lithium-ion battery.
Rechargeable lithium-ion batteries have become incredibly popular for smartphones, laptops, personal digital assistants (PDAs), and other portable electronic devices. There are many reasons why so many manufacturers have adopted rechargeable Li-ion batteries, for example:
Li-ion batteries used in watches are small. Despite their size, their 3 Volt capacity has a lifespan of as much as a decade in a low-drain watch.
The benefits of rechargeable lithium-ion batteries are very familiar to anyone with a smartphone or one of the latest lightweight laptop computers. Compared to lead-acid batteries, lithium-ion batteries are smaller in size and lighter.
In addition, they can withstand more movement and changes in temperature and still maintain power delivery while in use.
Charging of Li-ion batteries can be done much quicker than a lead-acid battery. Thanks to custom Li-ion battery options, it&#;s now possible to swap out existing battery technology for more efficient and longer-lasting portable power packs.
A rechargeable lithium-ion-powered personal mobility scooter can go a long way. The range can be as much as twelve miles.
One of the main benefits of using lithium-ion batteries is they are lightweight. Users can easily carry the battery indoors for recharging.
In addition, lithium batteries are the perfect green alternative to lead-acid batteries, are longer lasting, and charge faster. Less weight also means an extended travel range and less mechanical wear and tear.
Solar power is something the world is looking to rely on more and more. In the United States alone, it is predicted that solar will provide 20% of the country&#;s energy needs by the year .
Lithium batteries are ideal for energy storage and can be used to store the excess power produced by solar panels. Let&#;s face it, even in the middle of the desert, there are days when the sun doesn&#;t shine. There are also going to be times when the solar equipment needs repairing. Using lithium-ion batteries for energy storage means there are no occasions when you find yourself left in the dark.
One of the reasons lithium batteries are used for solar energy storage is that they match the panels in how they charge. How fast they charge is another reason. Lithium batteries require low-resistance charging, which is what solar panels produce.
The fact that these batteries charge so quickly also allows users to maximize the potential energy storage of solar power for every minute of sunlight available.
Even in today&#;s modern world, there are issues with power instability &#; or worse &#; power loss. Lithium technology is commonly used for emergency power backup or UPS battery models.
Using a lithium battery for backup is different from relying on a generator or other backup energy system. It will provide almost instant power, which is crucial if critical equipment needs to be connected to a constant power supply.
Lithium batteries and the backup power they can provide benefit a range of critical equipment such as medical technology, communication technology, and computers.
A hard-wired electricity supply is no longer essential if you want to monitor remote locations, a fleet of vehicles, a temporary location, or various job sites. You can use Li-ion batteries instead to power an alarm or surveillance system in remote or difficult locations with no access to an electrical grid.
The qualities that make Li-ion batteries so useful are their small size, long life, and the fact that they don&#;t lose power by way of self-discharge when the system they power is inactive. The low self-discharge rate of a typical lithium-ion battery is ten times lower than a traditional lead-acid battery. Lithium batteries are the ideal solution if a system is not continually in use.
People with mobility issues have found new freedom thanks to rechargeable lithium-ion batteries. They can be used in a variety of ways to make lives easier. Millions of people around the world now depend on stairlifts, electric wheelchairs, and mobility scooters.
The reliability of a Li-ion battery and the mobility technology it powers allows them to live a more independent life.
As in their many other applications, lithium batteries are lightweight, have a longer life span, and have a low self-discharge rate. They also offer an extended run time, size customization, and fast charging. Hence the popularity of large lithium-ion batteries for electric automobiles.
While lead-acid batteries were the traditional choice for electric vehicle applications like golf carts and trolley makers, more are now choosing lithium batteries. As long as your electric golf trolley uses the same energy connector, you can swap out the lead-acid battery for a lithium-ion battery.
You can expect Li-ion battery systems to have a long cycle life of between 1,000 and 2,000 charging cycles. How long the battery lasts depends on how frequently you play golf and how often you charge the battery.
If you play golf twice a week, that&#;s 2 x 52 weeks = 104 charging cycles per year. This means you can expect a lithium-ion battery to last a minimum of ten years. For more information, read our guide on golf cart batteries.
A marine battery is a specialized type of battery designed specifically for use in marine vehicles, such as boats, yachts, and other watercraft.
