With the rapid development of the lithium battery automobile industry, the problem of PACK connection of lithium batteries has become more and more prominent. Many bus vehicles have a dry battery group. The positive and negative materials of the single battery are aluminum foil and copper foil. How to realize the safe, reliable, light and simple string of lithium battery packs and the connection is the development of lithium battery Bottleneck technology.

 
Our company has developed two kinds of copper-aluminum composite materials connected by lithium batteries through independent innovation. Copper-aluminum composite pillar material and copper-aluminum composite transition sheet. Base column material: copper-aluminum composite pillar material made of 3mm copper material and 10mm aluminum plate composite, complete copper copper tandem connection of copper negative electrode, and aluminum and outer aluminum plate are connected to form two exposed electrodes of battery pack For the aluminum material, the normal laser welding process can be used to complete the connection: the connecting piece material: a 10mm copper strip is laminated in the middle of the aluminum plate, the copper strip is connected by the copper rivet and the internal copper galvanized, and the aluminum plates on both sides complete the single cell The series is connected in parallel. The product profile is as follows:
 
Product Size:
Customized according to user needs.
Features:
High composite strength, metallurgical bonding between copper and aluminum, no contact resistance between copper and aluminum, stable and reliable quality.
Technical Parameters:
Composite strength: >100MPa;
