32700 Battery Cap

The power battery with different positive materials and electrolytes has different characteristic temperature and voltage change curves during overcharge. Due to the overcharge protection function of the power battery cap, the charging will be forced to terminate when the overcharge reaches a certain degree. At this time, if the internal temperature of the power battery has reached the thermal runaway state, the internal pressure continues to rise, the explosion-proof film of the power battery cap will be broken, and the substances in the power battery will be ejected with the high-pressure gas.

1. With overcharge protection function

2. It can protect the power battery in case of external short circuit

3. Low internal resistance

4. It can ensure the safety performance of power battery

Each specification of the power battery cap is assembled by laser spot welding or hot pressing and made of aluminum, which further improves the stability of the explosion-proof system. When the internal pressure of the power battery reaches the specified blasting specification range, a large number of substances in the power battery are quickly discharged outward through the pressure relief hole of the top cover to ensure the safety performance of the power battery.

The power battery cap is very important and plays a very important role, so we must pay attention to its performance when using it.
