A nickel electrode for an alkaline storage battery 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.
A method of fabricating a nickel electrode for an alkaline storage battery comprising steps of:
- filling nickel hydroxide particles into pore of a porous sintered substrate,
- impregnating the sintered substrate having the nickel hydroxide filled with niobium salt, and
- depositing said niobium salt on the surface of the nickel hydroxide particles filled into the sintered substrate as niobic acid.
An alkaline storage battery provided with a positive electrode employing a nickel electrode for an alkaline storage battery, a negative electrode, and an alkaline electrolyte solution, wherein
- said nickel electrode for an alkaline storage battery is formed by filling an active material into pore of a porous sintered substrate, and
- said active material is formed by adhering niobic acid on a surface of nickel hydroxide particles.
