Zusammenfassung: | In a positive electrode for an alkaline storage battery, a layer is formed between a porous substrate as a core material and an active material including nickel hydroxide filled into the porous substrate. The layer includes an oxide containing cobalt and nickel and/or a hydroxide containing cobalt and nickel. In the hydroxide, the average of an oxidation number of a metal is more than +II. The layer has a high electric conductivity while keeping the high corrosion resistance. A utilization rate of the active material can be improved due to the high electric conductivity. An alkaline storage battery including such an electrode has a good cycle property. |
