Aluminum Foiled flexible busbar refer to the busbar as a composite of several layers of 0.lmm or 0.2mm thick aluminum foil. The structure of the busbar has two separated areas: solid and flexible.The solid area is welded by molecular diffusion welding machine and it is for cell/module connection in battery pack. The flexible area is not be welded during manufacture process and it will be beneficial for assembly and reliability for vibration.

Cu-Al compound busbar refer to the busbar which has two different materials: copper and aluminum.Cu-Al compound busbar is majorly used as module output busbar. Aluminum terminal will be in module and for laser welding, and Copper terminal will be out of module and for bolt/nut connection. Cu-Al compound busbar is produced by molecular diffusion welding or other advanced technology, not by ultrasonic welding.
