Abstract: PROBLEM TO BE SOLVED: To improve battery capacity per unit active material and to restrain the degradation of the battery capacity in conjunction with the progress of a charge-discharge cycle with great depth of discharge by forming a cobalt compound layer covering the surface of nickel hydroxide by including a fluorine resin in its inside. SOLUTION: Spherical nickel hydroxide containing a small amount of zinc or cobalt is deposited, for instance, from an aqueous solution and thereafter stirred at pH 9-10, a cobalt sulfate acidic aqueous solution where 50 wt.% of polytetrafluoroethylene is dispersed is added to it, and a fluorine resin is included in the inside and surface of cobalt hydroxide covering it. In addition, an active material is provided by cleaning it with pure water, and dehydrating and drying it. A cobalt compound layer containing polytetrafluoroethylene having a high binding force and water repellency is restrained from falling out from nickel hydroxide particles and eluted into an electrolyte in manufacturing an electrode, and its conductive matrix is hard to collapse.  It is recommended that this non-sintered type nickel electrode is made by filling the slurry of the active material in an active material holding body having a three-dimensional mesh structure.
