PURPOSE:To obtain a highly efficient and highly producible positive pole by mixing powdered dihydric cobalt hydroxide to an active material of which main component is nickel hydroxide at a specific mixing ratio through improving the utilizing ratio. CONSTITUTION:The mixing ratio of nickel hydroxide of an active material of a nickel positive pole to a powdered dihydric cobalt is made as 70-95:30-5. For example, after mixing and pulverizing, 5-30 percent of the powdered dihydric cobalt beta-Co(OH)2 and 95-75 percent of the powdered nickel hydroxide active material and a small amount of blending agent, it is pressed like a pellet and is covered with nickel net as a positive pole. Thereby, it enables to obtain a pole plate of high energy density and high producibility, improving a great deal of utilizing ratio of the active material. |
