PURPOSE:To obtain a nickel positive pole having high capacity density and active substance utilization with low cost, by filling nickel hydroxide with specific weight rate through electrolytic deposition and chemical impregnation. CONSTITUTION:Nickel hydroxide is filled by 90-60wt% in an electrode substrate through electrolytic deposition then filled by 10-40wt% through chemical impregnation. Alternatively nickel hydroxide is filled by 90-70wt% through thermal decomposition then filled by 10-30wt% through chemical impregnation. Alterntively a substrate impregnated with nickel nitrate is negatively decomposed in alkali solution then filled with nickel hydroxide by 90-60wt% thereafter filled by 10-40wt% through chemical impregnation. With such method a nickel positive pole having high capacity density to be employed in a nickel- cadmium cell can be obtained efficiently. |
