Description
In Lithium ion battery, the current collector of cathode has to be aluminum while at least the surface of anode current collector has to be copper. In metallurgy, copper and aluminum cannot be welded and that gives engineers a headache. Now, a new process is developed to make high quality copper aluminum composite material. Enhanced Materials Tech Co. Ltd.(Shanghai) Is the manufacturer and QSAM is the sole agent of the material in N.A.. To manufacturer the copper aluminum composite material, aluminum is directly casted on surface of existing copper plates. This allow the two metal join together perfectly. With years of optimization, the brittle transition layer of copper and aluminum has been minimized to less than 2um and the mechanical strength of copper aluminum bonding is extremely good. These advantages gives our copper aluminum bimetal high electrical conductivity and peel resistance. It could be further processed into all kinds of electrical connectors to reduce the process of connect copper and aluminum conductive parts together. It's also worth mentioning that the casting rolling process allow the production of thicker copper aluminum composite material, which could be a tough work for cold rolling line. Our regular thickness of the plates could be as large as 20mm.
