Why CATL and BYD adopt the
negative terminal for battery pack made by our Cu-Al bimetal
materials instead of previous negative terminal made by traditional
friction welding?
Production Advantages of our
new negative terminal:
1. Prepare
Cu-Al bimetal materials our company
produced.
2. Direct
Stamping on Cu-Al bimetal materials.
3. Single
machine can produce 20000pcs per day.
4. Normal
stamping machine can produce and no limit of production
capacity.
Production limit of negative
terminal made by traditional friction
welding:
1. Buy Copper
and Aluminum materials Separetely.
2. Welding
Copper and Aluminum together and more steps of
processing.
3. Single
machine can produce 7000pcs per day.
4. Only
friction welding machine can produce with limit
of production capacity.
Our Copper-Aluminum Bimetal Composites material is
a plating of copper on aluminum. The two metals
are combined together through
our patented technology which we
called Oxygen-free Semi-molten
rolling compound technology. This technology
solves the technical problems of oxidation and eutectic of
copper-aluminum composite.
