AI Technical Summary

Technical Problem

The end cap of the existing battery cell may short-circuit contact with the pole ear or adapter of the battery cell assembly, resulting in the risk of combustion or explosion.

Method used

An insulating protective layer is provided on the inner wall of the end cover of the battery cell, and the end cover is insulated and protected by the insulating protective layer, reducing the probability of the end cover coming into contact with the live structure.

Benefits of technology

It effectively reduces the probability of contact short circuit of the end cap, thereby reducing the probability of combustion or explosion caused by short circuit.
