Abstract
A nickel electrode for an alkaline storage battery in which an active material mainly containing nickel hydroxide is applied to a porous sintered nickel substrate, wherein a layer containing at least one hydroxide of an element selected from a group consisting of Ca, Sr, Sc, Y, lanthanoid, and Bi is formed on a surface of the active material thus applied to the sintered nickel substrate, or between the sintered nickel substrate and the active material.

A method of producing a nickel electrode for an alkaline storage battery, comprising:
- providing a porous sintered nickel substrate;
- applying an active material mainly containing nickel hydroxide to the porous sintered nickel substrate to form an active material layer;
- and
- forming a coating layer containing at least one hydroxide of an element selected from a group consisting of calcium Ca, strontium Sr, scandium Sc, yttrium Y, lanthanoid, and bismuth Bi on a surface of the active material layer thus applied to the porous sintered nickel substrate.
A method of producing a nickel electrode for an alkaline storage battery, comprising:
- providing a porous sintered nickel substrate;
- forming an intermediate layer containing at least one hydroxide of an element selected from a group consisting of calcium Ca, strontium Sr, scandium Sc, yttrium Y, lanthanoid, and bismuth Bi on the porous sintered nickel substrate;
- and
- applying an active material mainly containing nickel hydroxide to the porous sintered nickel substrate having the intermediate layer formed thereon, to form an active material layer.
A method of producing a nickel electrode for an alkaline storage battery, comprising:
- providing a porous sintered nickel substrate;
