AI Technical Summary

⚠Technical Problem

Existing busbars have high costs due to the use of copper plates and nickel sheets.

⚗Method used

Aluminum plates and nickel-plated steel sheets are used to replace copper plates and nickel sheets. Nickel-plated steel sheets are set on the aluminum plates for conductive connection with the electrodes of the cylindrical battery. The nickel-plated steel sheets include fixing sheets, welding sheets and connecting sheets. The structural design facilitates assembly and welding, and the enhanced deformation holes improve welding reliability.

🎯Benefits of technology

It reduced the cost of the busbar by about 50%, improved welding reliability, and reduced the welding defect rate.
