Copper-aluminum composite film connection

The copper-aluminum composite soft connection is made of 0.05-0.3mm thick copper-aluminum composite strip as raw material, and its interlayer metallurgical combination is formed by polymer diffusion welding. Compared with the traditional pure copper soft connection, the copper-aluminum composite soft connection can reduce the weight of the battery soft connection by 50%, the conductivity does not decrease compared with the pure copper ratio, and can improve the endurance of the car, which is an upgraded product of the current soft connection traditional products.
