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.
