PURPOSE:To ensure the high performance of a nickel-hydrogen storage battery and improve the productivity thereof by forming a nickel plate after oxidizing active material as a mixture of cobalt monoxide and active material mainly composed of nickel hydroxide, using an oxidizing agent, and combining the nickel plate with a hydrogen electrode. CONSTITUTION:Cobalt monoxide having a grain size of 1mum and a surface area of 70m<2> is mixed with peripheral nickel hydroxide containing 5wt% of cadmium hydroxide by a weight ratio of 95:5. The mixed active material so obtained is dissolved in a water solution mainly composed of potassium hydroxide having specific gravity of 1.35, and stirred. Then, K2S208 is added at a molar number equal to or above cobalt monoxide, and until oxygen gas is generated. The aforesaid mixed active material is filtrated, washed and dried. Thereafter, the material is made into paste state with CMC solution, and a nickel fabric porous body is filled with the paste. Furthermore, the body filled with the paste is dried at 80 deg.C for one hour and then pressed, thereby obtaining a nickel plate. According to the aforesaid construction, the utilization factor of the active material reaches 90%. |
