In an alkali storage battery comprising a positive electrode, a negative electrode and an alkali electrolyte in a battery can, .alpha.-nickel hydroxide containing manganese is used as a cathode active material for the positive electrode, and the difference between a charging potential and an oxygen gas evolution potential at the positive electrode is increased, to suppress oxygen gas evolution during the charging, and the volume percentage of the cathode active material and an anode active material is set to not less than 75 % in the battery can, to obtain a large battery capacity.
Accumulateur alcalin doté d'une électrode positive, d'une électrode négative, d'une solution électrolytique alcaline contenue dans un bac d'accumulateur, l'oxygène dégagé par l'électrode positive étant éliminé au moment de la charge de l'accumulateur. Pour ce faire, on augmente la différence entre le potentiel chargé et le potentiel générateur d'oxygène au niveau de l'électrode positive en utilisant du manganèse contenant de l'hydroxyde de nickel comme matériau actif de l'électrode positive et, on augmente simultanément la capacité de l'accumulateur en augmentant le volume occupé par les matériaux actifs des électrodes positive et négative de sorte qu'ils représentent au moins 75 % dans le bac d'accumulateur.
