AI Technical Summary
The existing cover plate assembly's riveting structure results in the poles and riveting blocks occupying too much external space of the battery cell, and welding different materials can easily lead to poor welding and insufficient pull-out force.
The cover plate adopts a reverse riveting structure, with the riveting block set below the cover plate body and the plate body of the pole set above the cover plate body. The pole body is welded to the riveting part of the same material, and the riveting hole is located in the area covered by the riveting part. The riveting block is made of copper-aluminum composite material.
This reduces the external space occupied by the battery cell, improves the connection strength and welding quality between the terminal and the rivet block, reduces resistance, and enhances the safety and reliability of the battery cell.
