Abstract

PURPOSE:To obtain a positive electrode in which no cracks, breaks and warps are developed by pressing and molding a unified body of a positive mixture and a resin net, and removing the said resin net by heat treatment. CONSTITUTION:After a metal mold is packed with a positive mixture powder consisting of a positive active material such as manganese dioxide, iron sulfide, copper sulfide, carbon fluoride or silver chromate, a conductive auxiliary agent such as flake graphite, and a binding agent such as polytetrafluoroethylene, the positive mixture powder is pressed from its upside so as to make the mixture powder to be molded preliminarily. After that, a resin net of around 40-60mesh, which is prepared by weaving thread, which has a diameter of about 0.07-0.1mm. and is made of polyethylene, polypropylene, nylon or the like, is placed on the positive mixture layer, and the positive mixture layer is pressed and molded. Next, thus molded body is subjected to heat treatment at a temperature within the range of 300-420 deg.C so as to make the former resin net to be decomposed, molten or evaporated, thereby removing the former resin net from the molded body.
