Nickel electrode for alkaline battery and battery using said nickel electrode.

摘要

A nickel electrode using a porous alkali-proof metal fiber substrate as a current collector and a nickel hydroxide powder as a principal component of active material is precluded from formation of the higher oxide, gamma -NiOOH, improved in the ratio of utilization of the active material, and enabled to enjoy high energy density and long service life when the nickel hydroxide powder employed therein is of a specific type possessing a pore radius in the range of 15 to 30 ANGSTROM , 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<2>/g. An alkaline battery is also provided by the invention which uses the nickel electrode described above.
