摘要
Provided is a positive electrode active material for an alkaline storage battery that can obtain high charging efficiency in a wide temperature range including under high temperature and can suppress self-discharge. The positive electrode active material for an alkaline storage battery contains nickel oxide, and in the powder X-ray diffraction image by the 2θ / θ method using CuKα ray of nickel oxide, the (001) plane peak intensity I001 with respect to the (101) plane intensity I101 The ratio FWHM001 / FWHM101 of the full width at half maximum FWHM001 of the (001) plane to the full width at half maximum FWHM101 of the (101) plane is 0.6 or less.
