How to extend the life of Lithium Battery?

Lithium Battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution.

Here are some ways to extend the life of Lithium Battery:

I. Charging

1. Avoid overcharging
-Most Lithium Battery devices have built-in charging protection circuits, but try not to connect the battery to the charger for a long time, especially after the battery is fully charged. Overcharging can cause overcharge pressure on the battery, leading to problems such as battery bulging and capacity reduction.
-For example, when your mobile phone or laptop shows that the battery is fully charged, you should unplug the charger in time.

2. Avoid over-discharge
-Do not let the Lithium Battery be completely exhausted before charging. Over-discharge may cause irreversible damage to the battery's electrodes and electrolyte. Generally speaking, you can consider charging when the battery has about 20% - 30% remaining.
-For some portable electronic devices, such as smart watches, if you often use the power to a very low level or even automatically shut down before charging, its battery life will be significantly shortened.

3. Use a suitable charger
-Be sure to use a charger that matches the specifications of the Lithium Battery. Different Lithium Batteries may have different voltage and current requirements. Using an inappropriate charger may cause the charging speed to be too fast or too slow, and may even damage the battery.
-For example, using a fast charging charger to charge a Lithium Battery device that does not support the fast charging function may cause additional burden on the battery.

2. Usage environment

1. Temperature control
-Lithium Battery works best in a suitable temperature range. Generally speaking, 0-40℃ is a more ideal operating temperature range.
-In a high temperature environment, such as leaving the Lithium Battery device in a hot car for a long time or charging in a high temperature environment, it will accelerate the aging of the battery and reduce the battery capacity and life. In a low temperature environment (below 0℃), the performance of the Lithium Battery will decrease. Although it will not cause serious damage to the battery life immediately, if it is frequently used at low temperatures and deeply discharged, it will also affect the long-term life of the battery.

2. Avoid humid environments
-Moisture may corrode the electrodes and circuit parts of the battery, so try to avoid the Lithium Battery from contacting a humid environment. If the Lithium Battery device is accidentally wet, it should be wiped dry immediately and placed in a dry environment for a period of time to ensure that the interior is completely dry before use.

3. Usage habits

1. Reduce high-power use
Using the Lithium Battery at high power, such as running the high-performance mode of a laptop at maximum power for a long time or letting power tools run continuously at high load, will generate a lot of heat and accelerate battery aging. When high performance is not required, the device can be adjusted to low power mode.

2. Regular charge and discharge cycles
Performing a complete charge and discharge cycle on the Lithium Battery every once in a while (such as a few months) can help calibrate the battery's power display system and help maintain the battery's activity. But be careful to follow the correct charge and discharge method to avoid overcharging and discharging.
