ABSTRACT:
A nickel electrode for an alkaline battery includes a porous alkali-proof metal fiber substrate as a current collector and an active material principally formed of a nickel hydroxide powder is precluded from formation of the higher oxide, .gamma.-NiOOH, is improved in the ratio of utilization of the active material, and is provided with a high energy density and a long service life when the nickel hydroxide powder employed therein possesses a pore radius in the range of 15 to 30 .ANG., a total pore volume of not more than 0.05 ml/g, and a specific surface area in the range of 15 to 30 m.sup.2 /g. An alkaline battery is also provided by the invention which uses the nickel electrode described above.
