How to Store a Lithium Ion Battery

How to Store a Lithium Ion Battery

To keep your lithium-ion battery in optimum condition, here are a few tips. First, always discharge your battery, and store it in a cool place with a temperature range of -20deg C to 60deg C. Once a year, you should charge it to 30 to 50 percent of its capacity.


Consumer product safety commission (CPSC) staff is currently reviewing and drafting a report on lithium ion battery recalls. Although CPSC guidelines are not directly enforceable, most responsible companies take them seriously. The CPSC has also used its “bully pulpit” authority to encourage manufacturers to adopt new voluntary standards. For example, the CPSC recently urged the adoption of a new UL standard for lithium ion hoverboard scooters.

When storing lithium batteries, it’s important to keep them at a constant state of charge (SoC) in a dry, refrigerated environment. Otherwise, lithium batteries will experience self-discharge, which significantly reduces their life span. Batteries should also maintain a maximum of 4.1 volts in order to maintain safety.

Lithium ion batteries should be kept dry and away from metal objects. Metal objects can short circuit the battery and damage the electrodes. Never leave a lithium battery in direct sunlight, in a vehicle, or on a tabletop. Also, don’t knock it over or bump it if it is charging. Lastly, lithium batteries should be kept at fifty to sixty percent charge when they are not in use. They should be recharged every three or six months. It is also recommended that batteries be kept in moisture-proof cases when not in use.

Although lithium ion batteries are not directly regulated by the government, they do need to be certified before they can be sold in the U.S., which means that they are governed by the CPSC. The CPSC’s guidelines are meant to protect consumers and ensure that these batteries are safe and effective.

Temperature range

Temperature range is a very important factor when using lithium ion batteries. A battery will degrade when the temperature is too high or too low, causing the cells to not perform at their best. The temperature range is limited for a variety of reasons, including the electrolyte that is used to store the lithium ions. Typically, this electrolyte is composed of volatile organic solvents and thermally unstable salts.

Lithium-ion batteries operate best between 70°F and 40°C, but they will lose their capacity at lower temperatures. They will also suffer irreparable damage to their separators if left in extreme temperatures. However, even though lithium batteries can function under very high temperatures, it is advisable to keep them out of extreme cold and heat to preserve their performance.

Lithium particle batteries can be charged in temperatures ranging from -5degC to 45degC, but this is not a good idea for consumer grade batteries. This is because the charge current will drop due to reduced diffusion rates on the anode and internal cell resistance. It’s also possible for metallic lithium plating to occur during sub-freezing charging.

Lithium ion batteries are sensitive to high temperatures, so proper charging and storage is essential. It is also important to avoid extreme temperatures, as they may affect the chemical reaction that takes place inside the battery cell. To avoid this situation, it’s important to use the right temperature control system.

CUSTOMCELLS(r) high-temperature technology provides superior intrinsic safety, reliability, and performance under extremely high temperatures. It is suitable for a wide range of applications, including safety-critical areas and hazardous environments. The company also offers feasibility studies and testing services.


One of the major safety concerns of lithium ion batteries is the possibility of overcharging them beyond their cut-off voltage. This requires a detailed understanding of the mechanism of battery overcharging to guide the design of battery systems. The current study evaluates a commercial pouch lithium-ion battery with a composite cathode under various test conditions. It focuses on the effect of the charging current and restraining plate over other factors such as heat dissipation.

Overcharging a lithium-ion battery will cause chemical reactions to take place inside the battery cell, degrading its components. Lithium plating, a deposit of metallic lithium on the anode, is another symptom of this damage. If you are unsure of how to safely recharge a fully discharged Li-ion battery, consider getting professional help.

Luckily, most lithium-ion batteries have an internal circuit that prevents overcharging. This prevents you from overcharging the battery, which can damage the battery’s performance and make it overheated. Most modern devices have a control unit that automatically shuts off charging when the battery reaches 100%. But if the control unit malfunctions, an overcharged battery can still cause the device to overheat, slow down, or even explode. Thankfully, these occurrences are rare, but they’re still a risk.

The temperature curve is divided into two distinct stages during overcharging. The 2C condition took about 57 s, while the overcharge stage lasted 1149 s. Once the battery reaches 100 percent SOC, the safety valve opens to release pressure. This is a clear indication that overcharging is not a good idea.

Lithium-ion batteries should never be charged in hot or high temperatures. This can damage the battery’s connections and shorten its life. It can also cause a fire if charged too quickly. In these cases, it is wise to replace the battery rather than recharge it.


During the overdischarge of lithium ion batteries, many reactions occur in the battery that are exothermic and lead to thermal runaway. One of the main effects of these side reactions is the generation of gas, which causes pressure to build up inside the lithium ion cells. This process is monitored and a mathematical model is derived to explain the relationship between the state of charge, temperature, and internal cell pressure.

The initial discharge process of a lithium ion battery causes the extraction of lithium ions from the anode and their transfer to the cathode through electrolytes. The lithium ions then intercalate into the crystal of the cathode. The internal resistance of the battery increases dramatically because the ions are now metallic.

The final capacity of the battery after overcharging is approximately one-third of its initial capacity. This is equivalent to a charge rate of approximately 2 A/h. However, the final capacity of the battery depends on the actual type of battery. A battery that is overcharged to its capacity limit will fail.

Excessive overdischarge can lead to the formation of solid-state amorphous lithium metal compounds. This degradation of the capacity of lithium ion batteries affects the lifespan of the battery. It also leads to the dissolution of the Cu collector, which can result in the battery deteriorating prematurely.

XAFS analysis of the discharged cells revealed the presence of copper species. Copper ions are present on the negative and positive electrodes, and are carried through the electrolyte as a result of the overdischarge process.

Disposal of damaged or overcharged batteries

When disposing of damaged or overcharged Lithium-Ion batteries, remember to follow proper procedures. Avoid placing the batteries in the garbage, putting them in water, or allowing them to sit in a warm place. If possible, store the batteries in fire-proof containers. Contact a battery disposal service for advice. Damaged or overcharged batteries can pose a serious health risk and should be properly disposed of.

To prevent fires from spreading, isolate lithium-ion batteries from each other in bulk storage areas. This will ensure that the fire does not spread throughout the battery store. The batteries should also be stored in an area with a fire-retardant barrier to allow personnel time to evacuate and use fire-extinguishing equipment if needed. For flammable materials, keep the temperature of the surrounding area to less than 15°C, so that there is little risk of fire spread.

Lithium-ion batteries are increasingly popular in consumer electronics. Increasing use of electric vehicles will increase the size and number of battery packs in storage. The Foundation’s Property Insurance Research Group has researched the potential fire hazards associated with lithium-ion storage and developed technical recommendations to help prevent them.

Lithium-ion batteries have long shelf lives, lasting as many as 500 charge cycles. However, over time, they will become less efficient and eventually unusable. To maintain battery performance, routine inspection and charging and discharging are essential. Be aware of signs of damage, such as swelling or discoloration.
