Metal dynamic composite bi-metal tab terminal, post terminal, and current busbar can save assembly costs, which is the first choice for lithium-ion battery manufacturers. Copper-aluminum conductive transition joints are suitable for the transition connection of the conductive bus and copper-aluminum bus in graphite furnace in carbon factory.
Phohom's power battery structural parts has a high bonding strength, reducing resistance, and can avoid the risk of electric puppets that are prone to occur during conventional dissimilar metal welding. It can provide strong support for power battery carrier load and electrical energy storage.
