摘要： PURPOSE:To improve the utilization factor of a positive electrode by forming a mixture including nickel hydroxide and cobalt monoxide in which its surface is covered with a high-order cobalt oxide layer on a conductive core body. CONSTITUTION:A non-sintered type nickel positive electrode 1 is spirally wound with a separator 3, composed of a synthetic-resin-made nonwoven fabric, interposed in a space with a hydrogen occluded alloy negative electrode 2 including hydrogen occluded alloy powders, and is housed in a bottomed cylindrical vessel 4. Also an alkaline electrolyte is put in the vessel 4. The hydrogen occluded alloy negative electrode 2 has structure in which a mixture, having composition in which the hydrogen occluded alloy powders and conductive material powders and a binding agent are blended, is formed on a conductive core body, an electricity collecting body, and has a capacity in a range of 1.0-2.5 times the sum of the capacity of the nickel hydroxide of the positive electrode 1 and an electricity quantity needed for oxidizing cobalt monoxide. This improves a positive electrode 1 utilization factor and betters a charge and discharge characteristic at large current.
