AI Technical Summary

Technical Problem

In the existing technology, the method of connecting the base plate and the insulating film through hot melting increases the complexity of the manufacturing process and the cost of auxiliary materials. It also has problems such as weak connection, warping or melting through, which affect the quality and reliability of the battery cell.

Method used

Spacers are installed in the area near the end face of the bare cell. The spacers are formed by bending the insulating film, which replaces the hot-melt bottom support to protect the bare cell. This avoids damage and material loss caused by vibration and displacement during the casing process, simplifies the process and reduces the cost of auxiliary materials.

Benefits of technology

By setting spacers, the product quality and reliability issues caused by the hot-melt process were resolved, the process flow was simplified, the cost of auxiliary materials was reduced, and the protection effect and structural consistency of the battery cell assembly were improved.
