PURPOSE:To provide a complex positive electrode having high capacity and long lifetime by covalently binding an inorganic positive electrode active substance with an organic positive electrode active substance through a treatment with silane coupling agent solution, and subjecting the resultant to mixed pressurization or permeation. CONSTITUTION:A positive electrode is formed through two processes; i.e., a one in which at least either of the powder formed inorganic active substance and powder- formed or film-shaped organic active substance is treated with silane coupling agent solution, and another process in which powder formed inorganic and organic active substances are mixed and pressurized, or otherwise powder formed inorganic active substance is pressurized and permeated into film-shaped organic active substance. Covalent bond using silane coupling agent is strong to allow the inorganic and organic active substances to form a composite body with close contactness, and the mutual complementing action of the two active substances is promoted. This can be done with less amount of conductive materials such as carbon and binding material such as teflon, and a complex positive electrode with increased discharge capacity, high capacity, and long lifetime will be obtained. |
