PROBLEM TO BE SOLVED: To provide an alkaline storage battery with high charge accepting capability, even when it is left to standing after a deep discharge has been made, high capacity recovering capability in charging, high positive active material utilization factor almost similar to the initial discharge even in the discharge in the case in which it was left to stand after the deep discharge, and moreover good discharge characteristics even under low temperature atmosphere at 0 deg.C or lower by improving a positive electrode of the alkaline storage battery. SOLUTION: In an alkaline storage battery comprising a positive electrode 1 prepared by filling nickel hydroxide in a porous substrate as the active material, a negative electrode 2, a separator 3, and an alkaline electrolyte, the positive electrode 2 is made mainly of nickel hydroxide powder, and lithium cobalt composite oxide powder and divalent cobalt oxide powder and/or metallic cobalt powder are added to the nickel hydroxide powder. |
