Lithium Batteries

Lithium-ion battery is a high-capacity rechargeable battery developed in the 1990s. It can store more energy than nickel-hydrogen batteries, has a large specific energy, long cycle life, low self-discharge rate, no memory effect and environmental pollution, and is a hotspot of storage technology research in various countries today, mainly focus on three aspects of large capacity, long life and safety.

Lithium ion battery is a kind of secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive and negative electrodes to work .During the charging and discharging process, Li+ intercalates and  de intercalates back and forth between the two electrodes: during charging, Li+ de intercalates from the positive electrode and inserts into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.

Precautions for use and maintenance
1- Avoid using under severe conditions, such as: high temperature, high humidity, prolonged exposure in summer sun, etc., avoid throwing the battery into a fire.
2- When installing or removing the battery, make sure that the electrical appliance is in the power off state.
3- The operating temperature should be kept between - 20~50≧.
4- Avoid long-term "storage" of batteries in electrical appliances that are no longer in use.
