ALKALINE STORAGE BATTERY

PROBLEM TO BE SOLVED: To provide an alkaline storage battery that prevents the lowering of conductivity even when a charge/discharge cycle is repeated under a high-temperature atmosphere and has excellent cycle characteristics at a high temperature. SOLUTION: The alkaline storage battery has a cobalt compound layer on the surface of a positive electrode active material composed mainly of a nickel hydroxide. At least one compound selected from among niobium compound, titanium compound, tungsten compound and molybdenum compound is added into the cobalt compound layer. An alkaline electrolyte composed mainly of a potassium hydroxide contains a lithium hydroxide, and the content of the lithium hydroxide is controlled to 0.6-1.6 mol/L, whereby the niobium compound, titanium compound, tungsten compound and molybdenum compound can be prevented from being dissolved out in the alkaline electrolyte to retain a favorable conductive network.
