Positive active material for alkaline battery nickel electrode

摘要

Positive active material for nickel electrode of alkaline battery consists of hydroxide particles principally of nickel. The particles are coated with layer of phase consisting of hydroxide based on nickel and yttrium, containing 0.15-3 wt.% yttrium with respect to total weight of particles. Also claimed are method for making the material, and its use in nickel electrode.
