PURPOSE:To provide the manufacture of a nickel electrode for an alkaline storage battery improving the utilization factor of an active material and increasing the volume efficiency and weight efficiency at a low cost, particularly the manufacture of the nickel electrode used for the alkaline storage battery such as a nickel-cadmium storage battery or a nickel-hydrogen storage battery. CONSTITUTION:A nickel electrode obtained by directly using nickel hydroxide has the utilization factor of nickel hydroxide slightly lower than that of the sintered type. Cobalt is effective in particular including the sintered type to improve the utilization factor, however, the absolute capacity is decreased if too much cobalt is added. The nickel electrode used for an alkaline storage battery is mainly made of nickel hydroxide added with cobalt powder, and it is heated at 120-170 deg.C in the atmospheric air so that the low potential caused by cobalt is not extinguished. Carbonyl cobalt is preferable for the cobalt used here, and the cobalt powder about 3-15wt.% is preferably added to nickel hydroxide. |
