PROBLEM TO BE SOLVED: To construct light a secondary battery with a nonaqueous electrolyte using a lightweight current collector by forming the collectors of the positive and the negative electrode from a conductive film of resin where a conductive metal is provided as the surface layer. SOLUTION: A nonaqueous electrolyte secondary battery concerned is composed of a positive electrode made of Lix MO2 (M is one of the elements Ni, Co, Fe, and Mn) and a negative electrode made of lithium metal, lithium alloy, or a carbonic substance capable of doping and dedoping the lithium. If a conductive film of resin having a conductive metal as the surface layer is used for the current collector of both or either of the positive and negative electrodes, the collector can be made light in weight, which should lead to a lightweight construction of the resultant secondary battery. |
