PURPOSE:To obtain a paste type electrode having the excellent capacity holding characteristic by filling clearances of a nickel porous sheet as a base with the paste material including the active material, and after dipping it in the alkaline aqueous solution, washing it with hot water. CONSTITUTION:Clearances of a nickel porous sheet are filled with the active material paste, which is obtained by mixing nickel hydroxide, conductive assistant, binder, thickener and water, to form a sheet electrode. This sheet electrode is dipped in the alkaline aqueous solution to eliminate the binder and the thickener. Thereafter, this sheet electrode is washed with hot water to eliminate the residual material dissolved in the alkaline aqueous solution. This nickel electrode is used for a positive electrode 1 of an alkaline storage battery, and a hydrogen storage alloy electrode is used for a negative electrode 2, and a separator 3 is interposed between them to form an alkaline storage battery, and in this alkaline storage battery, self-discharge is reduced and the capacity holding characteristic is improved. |
