(57) [Abstract] An alkaline storage battery using a nickel electrode is provided. Improving the charge acceptability after leaving the deep discharge being performed and improving the capacity recovery after charging, and at the time of subsequent discharge, a cathode active material utilization almost equal to the initial one can be obtained. Provide long-life alkaline storage batteries. SOLUTION: In an alkaline storage battery comprising a positive electrode in which a porous substrate is filled with nickel hydroxide as an active material, a negative electrode, a separator, and an alkaline electrolyte, the positive electrode comprises: It contains nickel hydroxide powder as the main component and a composite oxide of lithium and cobalt. |
