High conductivity double shiny ED copper foil for Lithium-ion battery Lib notebook PC
single side treatment low profile foil in red.
Width: 5-520 mm
Length: 500-5000 M
ID: 76 mm,152 mm
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.
1. Lib: notebook PC, mobile phone.
Compare between CA copper foil and ED copper foil
1. Width: rolling copper foil width ≤ 620mm, electrolytic copper foil width ≤ 1380mm
2. Density: rolled copper foil higher density, the surface is relatively smooth, conducive to the production of printed circuit board after the rapid transmission of the signal, so high-frequency high-speed transmission, fine lines printed circuit board also used some calendering copper Foil.
