(57) Abstract: An active material powder comprises nickel hydroxide-containing base particles, a coating inner layer of cobalt or a cobalt compound coating the base particles, and yttrium and scandium coating the coating inner layer. Or lanthanoid, Alternatively, it is composed of composite particles composed of a coating outer layer made of such a compound. The present invention provides a non-sintered nickel electrode for an alkaline storage battery that exhibits a high active material utilization rate not only when charged at room temperature but also when charged under a high temperature atmosphere. |
