PURPOSE:To aim at enhancement of utility rate of positive pole active material, by a method wherein, after at least a part of binder is dissolved in organic solvent and depolarizer for battery is mixed in intra-oil water drop type emulsion in which water is dispersed in form of corpuscles, depolarizer for battery is placed on a current collector and drying process is applied thereon. CONSTITUTION:An electrode for battery is formed by having at least a part of binder dissolved in organic solvent, depolarizer for battery being mixed in intra-oil water drop type emulsion in which water is dispersed in the organic solvent in form of corpuscles, and having said depolarizer placed on a current collector material before a drying process applied thereon. Namely, positive pole depolarizer ink is applied on a positive pole current collector 2 through the process of screen printing and a drying process is applied thereon to form a positive electrode 4. A flat battery A is formed by using this positive electrode 4. Negative pole depolarizer 6 consisting of zinc powder and binder is opposed to a negative electrode applied on a negative pole current collector 7, via a separator 5 made of polyester unwoven cloth in which the positive electrode 4 is impregnated with electrolytic liquid consisting of water solution of zinc perchlorate, and the peripheral edge of the battery is tightly sealed by means of an insulation film of three-layer structure composed of polyethylene/ polyethylene terephthalate/polyethylene. |
