Li-ion Battery Cathode Basic Material Lithium ED copper Foil
Description :
CCL/PCB electrolytic copper foil are classified as :Standard electrolytic copper foil(STD),High-temperture elongation of the copper foil( HTE) ,ultra-low contour copper foil(VLP), flexible copper foil(FCF),inversion of opper foil(RTF).Ordinary thickness of the ED copper foils are 6 microns and 8 microns ,12 microns ,18 microns,35microns ,105 microns, 400 microns,etc. The maximum width of the ED copper foil iw 1370mm(53.93inch),.Also we can do special process according to customer requirements .
