| titleOfInvention | Method for producing nickel positive electrode for alkaline storage battery and alkaline storage battery |
| abstract | [PROBLEMS] To prevent corrosion of a nickel sintered substrate for an alkaline storage battery, maintain good electrical conductivity between a substrate and an active material, to have a good utilization rate of a positive electrode active material, and to greatly reduce a discharge voltage of a battery. To obtain a nickel positive electrode for an alkaline storage battery that does not reduce the charging efficiency in the positive electrode active material charging operation without performing the above. SOLUTION: A porous nickel sintered substrate is oxidized in air to form a nickel oxide layer on the surface of the substrate, and then the substrate is immersed in an alkali solution, washed with water and dried, and then immersed in an aqueous solution of acidic cobalt salt. Dipping and drying, then dipping in an alkaline aqueous solution, and then drying in air at 100 to 150 ° C. to form a cobalt oxide film having a valence of more than 2 on the surface of the nickel oxide layer After that, an active material filling operation involving impregnation with an acidic nickel salt is performed.
