Charging and precautions for polymer lithium batteries.

Charging and precautions for polymer lithium batteries:

At present, the charging method of polymer lithium batteries generally adopts constant current and constant voltage charging: the battery is first charged with constant current CC. When the battery voltage rises to a certain value (4.2V), the voltage remains unchanged CV, and the current in the circuit drops very small, eventually approaching 0.

1. Do not charge the battery near a fire or in a very hot place;
2. Do not put batteries in microwave ovens or high-voltage containers;
3. It is prohibited to use or place batteries in high temperatures (such as strong sunlight or very hot cars) for a long time, otherwise it may cause battery overheating, fire, functional degradation, and reduced lifespan;
4. If there is electrolyte leakage that comes into contact with the skin or other parts, immediately rinse with water. If the electrolyte comes into contact with the eyes, immediately rinse with water and seek medical attention nearby;
5. It is prohibited to use damaged batteries. Batteries that leak electrolyte or emit electrolyte odor should be kept away from sources of fire to avoid battery ignition or explosion.
