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.
Claims7
A sintered nickel electrode for an alkaline storage battery in which an intermediate layer of an active material mainly containing nickel hydroxide is applied to a porous sintered nickel substrate, characterized in that a coating layer consisting of at least one hydroxide of an element selected from the group consisting of strontium Sr, scandium Sc, yttrium Y, the lanthanoid elements, and bismuth Bi is formed on a surface of the intermediate layer opposite the porous sintered nickel substrate.
A sintered nickel electrode for an alkaline storage battery in which an intermediate layer of an active material mainly containing nickel hydroxide is applied to a porous sintered nickel substrate, characterized in that a coating layer containing cobalt together with at least one hydroxide of an element selected from the group consisting of calcium Ca, strontium Sr, scandium Sc, yttrium Y, the lanthanoid elements, and bismuth Bi is formed on a surface of the intermediate layer opposite the porous sintered nickel substrate.
