PROBLEM TO BE SOLVED: To provide a nickel electrode plate for an alkaline storage battery of which, the lowering of big current charging property and big current discharging property are restrained instead that the surface of a positive electrode active material is covered by the element of Ca, Sr, Y, Al, Mn, or the like. SOLUTION: The surface of a porous conductive base board of the nickel electrode plate for the alkaline storage battery is covered by cobalt-containing oxide, and the surface of positive electrode activator is covered by compounds including the elements chosen from Ca, Sr, Sc, Y, Al, Mn, and lanthanide group elements. By covering the surface of positive electrode active material with compounds including the elements chosen from Ca, Sr, Sc, Y, Al, Mn, and lanthanide group elements, the increasing effect of oxygen overvoltage becomes big, and discharge receptivity is improved, and according toe the improvement of the conductivity between the porous conductive base board and the positive electrode active material due to the cobalt-containing oxide, the lowering of big current charging property and big current discharging property are restrained. |
