ALKALISCHE SPEICHERBATTERIE UND VERFAHREN ZUM LADEN DIESER BATTERIE

摘要

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.
