Battery cover helium detector equipment

Date:2022-03-29 Views:4194

The main function of the cathode material lithium battery cover plate is to effectively increase the current-carrying area of the contact surface between the boss and the conductive sheet, reduce the overcurrent, and decrease the probability of the flip chip being blown. Thus, it can effectively reduce the risk of the power battery catching fire or exploding, and greatly improve the safety performance of the power battery.

The inside of the power battery casing mainly contains organic electrolyte and a special separator. The cover plate mainly contains an explosion-proof valve, pole posts, a safety cap, a liquid injection hole, etc. The sealing and welding requirements between the casing and the cover plate are very high. The welding quality directly affects the sealing degree of the battery. Poor welding will lead to problems such as battery leakage, lithium precipitation, and unqualified battery appearance.

In the cost composition of lithium batteries, especially in the cost composition of square aluminum-shell lithium batteries, the casing accounts for about 16%.
