6um Double Shiny ED Copper Foil For Li - ion Battery With Good Performance
Product Description
The normal thickness of this kind copper foil dedicated to lithium battery is 6~20microns for single-sided and double-sided. The width ranges from 100 mm to 1340mm.Double-sided ED copper foil have performances of double side structure symmetrical, density of metal closing to copper theoretic density, low surface contour and great extension and tensile strength. When collected with cathode materials of li-ion battery, the touch area is large than use single matte and double matte ED copper foil. It decreasing the resistance between the cathode collectors and the cathode materials to enhance symmetry of volume capacity and structure of the battery. At the meanwhile, double-sided optical electrolyzed copper foil cathode collector has wonderful resistance cold and thermal expansion performance ,which can obviously extend life of the battery.
