Lithium-ion batteries, despite their impressive energy density and long lifecycle, come with potential safety risks. When the internal pressure of a battery exceeds a certain threshold, it can lead to catastrophic failures, such as thermal runaway, leakage, or even explosion. To prevent such disasters, lithium-ion batteries are equipped with safety mechanisms, including valves that control and regulate internal pressure. These valves help maintain a safe operating environment by venting gases, relieving excess pressure, and preventing dangerous leaks.
