ED copper foil for Li-ion Battery (Double-shiny)
Type
Lithium Battery Copper Foil
Thickness Range
8um-35um
Width Range
100~1300mm
Performance
The symmetrical structure of both
sides
The metal density nearing the
copper theoretical density
Very low surface profile, high
elongation and tensile strength
Application
Be
used for the Li-ion battery cathode carrier and current collector.
Advantages
Comparing with the single matte and double matte ED copper foil, when it adheres with the cathode material, the contact area will increase dramatically, it can distinctly reduce the contact resistance between the cathode current collector and the cathode material; the cathode current collector of the foil also has excellent resistance of the cold and heat expansion, it can obviously increase the service life of the batteries.
