18650 battery busbar application

Copper-nickel composite strip is a composite metal material formed by bonding pure copper strip and pure nickel strip into one through a rolling composite method. It is then processed to the required size through stamping and etching, and made into various busbars. The composite material has good metal solubility, no delamination occurs between the metals, and at the same time, its electrical conductivity and welding performance are improved.

Product summary:

This product has good electrical conductivity and weldability, and is currently mainly used for busbars in power battery packs.

Product Features:

(1) Safer and more reliable: No transfer welding, no cold solder joints, fusible, integrated design, shock resistance is more guaranteed;

(2) Flexible design: multi-metal local composite concept, high conductivity, and easy to weld;

(3) More economical, faster turnaround: saves on mold making and welding transfer.
