COMPOSITE CURRENT COLLECTOR |
| 摘要 |
A current collector effective for reductions in weight and thickness. The current collector produced by forming a conductive layer having a surface electric resistance not higher than 1.3 OMEGA /cm on the surface of a resin film and then forming an electrolytic plating layer having a thickness of at least 0.3 mu m per one side, characterized in that the surface electric resistance is not higher than 40 m OMEGA /cm after electrolytic plating and following expression is satisfied; Y1+Y2+Y3 </=0.8x ((X 1+X2+X3 ) xY3/X3) where, X1: thickness of resin film( mu m), X2: thickness of conductive layer ( mu m), X3: thickness of plating layer ( mu m), Y1: weight of resin film (mg/cm<2>), Y2: weight of conductive layer (mg/cm<2>), and Y3: weight of plating layer (mg/cm<2>). <IMAGE> |
