Valves are critical components in lithium battery systems, particularly in lithium-ion cells. They serve various functions, including pressure regulation, thermal management, and safety enhancement. In battery applications, valves allow for the controlled release of gases generated during charging and discharging cycles, preventing excessive pressure build-up that could lead to battery failure or even catastrophic events, such as explosions or fires. Moreover, high-quality valves are essential for maintaining the longevity and efficiency of lithium batteries.
