What are the considerations in material selection for lithium battery safety valves?

The selection of materials for lithium battery safety valves is extremely important, as it will directly affect the performance and reliability of the safety valve. When selecting materials for safety valves, some main considerations include the chemical stability of the material, the The main function is to ensure the safe operation of the battery. Therefore, it needs to have excellent chemical stability to ensure long-term stability in the environment inside the lithium battery without corrosion, deterioration or other chemical reactions.

High temperature resistance is also a must-have characteristic of the raw materials for making lithium battery safety valves. Since lithium batteries may generate high temperatures when working, in order to prevent the safety valve from deforming, softening, etc. in a high temperature environment, which may cause the safety valve to fail. , the raw materials must have high temperature resistance.

In addition, the material used to make the lithium battery safety valve needs to have sufficient pressure resistance to withstand the internal pressure of the lithium battery when it is working, to prevent the material from rupturing due to excessive pressure.
