In a sintered nickel electrode for alkaline storage battery formed by filling nickel hydroxide as an active material into a porous sintered substrate and an alkaline storage battery using as its positive electrode the sintered nickel electrode for alkaline storage battery, tungstic acid is adhered to a surface of said nickel hydroxide as an active material.

Sintered nickel electrode for alkaline storage battery, method of forming the same, and alkaline storage battery

The nickel electrode for alkaline secondary battery according to the present invention is obtained by applying a paste containing active material particles comprising nickel hydroxide to a conductive substrate and drying the paste on the conductive substrate. In the above-mentioned nickel electrode for alkaline secondary battery, a conductive layer comprising sodium-containing cobalt oxide is formed on a surface of the active material particles and tungsten powder and/or tungsten compound powder is added on the active material particles.

Nickel electrode for alkaline secondary battery and alkaline secondary battery

A nickel electrode for an alkaline storage battery employed as a positive electrode of an alkaline storage battery is formed by filling an active material into pore of a porous sintered substrate wherein said active material is formed by adhering niobic acid to a surface of nickel hydroxide particles.
