1. We can provide the specific single-matte, double-matte and most importantly double-shiny ED copper foils with the nominal thickness from 6μm to 35μm for Li-ion battery with width from 100mm to 1300mm.
2. Double shiny ED copper foil has the characteristics of symmetrical structure of both sides, metal density quite near the copper theoretical density, very low surface profile and high elongation and tensile strength.
3. Compared with single-matte and double-matte ED copper foils, when it adheres with the cathode materials, the contact area will increase dramatically, it can distinctly reduce the contact resistance between the cathode current collector and the cathode material.
4. The cathode current collector of the foil also has excellent resistance of the cold and heat expansion, increasing the service life of the batteries.
