Lithium batteries, while efficient and powerful, require careful management to ensure their safety and longevity. One of the critical components in the design of lithium batteries is the valve, which plays a crucial role in regulating internal pressure and preventing potential damage or even catastrophic failure. As batteries charge and discharge, chemical reactions can produce gas, which may build up internal pressure. If not properly managed, this pressure can lead to dangerous situations such as leakage, swelling, or even explosion. Therefore, high-performance valves are essential to maintaining the safe operation of lithium batteries.
