Abstract

PURPOSE:To provide an alkaline battery having good storage life by forming a polyvinyl pyrrolidone film on the surface of positive mix to prevent breakdown of positive mix molding or movement of positive mix particles toward a negative electrode. CONSTITUTION:A solution prepared by dissolving polyvinyl pyrrolidone in a solvent is applied on the surface, which is to be in contact with a separator 4, of a positive mix molding 2, and dried to form a film 3 of polyvinyl pyrrolidone. The film 3 of polyvinyl pyrrolidone prevents breakdown of positive mix molding 2 or movement of positive mix particles toward a negative electrode. Since the polyvinyl pyrrolidone film swells by contacting alkaline electrolyte, electrolyte exists near the positive mix, and no battery reaction is disturbed.
