PURPOSE:To obtain good cycle characteristics and high rate discharge characteristics by putting a collector of a thin foil between powders of positive pole active material and sheets of mixed agent, and providing a highly conductive layer on the surface of the sheet of the mixed agent in contact with the collector. CONSTITUTION:A collector of aluminum foil, for example, put between sheets of positive pole mixed agent is used for a positive pole thin layer sheet. For the positive pole mixed agent sheets, powders of positive pole active material of LiV3O2 is used for example, powders of acetylene black is used for conductivity assisting agent, and these are mixed and formed into a sheet using binding agent of Teflon binder. This positive pole mixed agent sheet is used having a conductive layer of a higher conductivity than the positive pole mixed agent sheet applied on one side. |
