PURPOSE:To enhance the utilization of active material and high rate discharge performance by mixing specific divalent cobalt compound powder and metallic cobalt powder with nickel hydroxide powder, and filling an alkali resistant porous substrate with the mixture. CONSTITUTION:One of CoO, alpha-Co(OH)2, and beta-Co(OH)2 powder which are divalent cobalt compounds and metallic cobalt powder are mixed with nickel hydroxide powder. An alkali resistant porous substrate is filled with this mixture to form a nickel electrode. An alkali storage battery is manufactured by using this nickel electrode. In the mixture of divalent cobalt compound powder and metallic cobalt powder, it is preferable that the content of the metallic cobalt powder is 75wt.% or less. The alkaline storage battery in which the utilization of active material and high rate discharge performance are enhanced is obtained. Discharge reserving amount is easily controlled and productivity is increased. |
