(FR2760567-A1)      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.    USE -   As active material for positive electrode in alkaline battery (claimed), the electrode containing binder comprising at least one compound selected from carboxymethylcellulose, hydroxyethylcellulose, and hydroxypropylcellulose; and at least one compound selected from polytetrafluoroethylene, and polytetrafluorovinylidene.    ADVANTAGE -   Material avoids problems encountered in earlier work due to incompatibility between compounds used in electrode; and it improves retention of charge, and reliability of battery.
