Lithium batteries are known for their high energy density and long life cycles, but they also come with inherent safety concerns. A key aspect of ensuring the safety of these batteries is the integration of a valve system, which helps regulate internal pressure and prevent dangerous over-pressurization. During normal operation, a lithium battery may undergo changes in pressure due to temperature fluctuations, charging, or discharging cycles. A valve in the battery provides a controlled release of pressure when it exceeds a certain threshold, preventing damage, leakage, or even explosions.
