Abstract

Improvements in high consumption alkaline batteries, comprising a negative electrode, a mixed bivalent silver oxide and monovalent silver oxide depolarizer, a separator between said negative electrode and the mixed depolarizer and an aqueous potassium hydroxide electrolyte containing said up to about 70% by weight mixed depolarizer of bivalent silver oxide and a substantially continuous silver layer permeable to the electrolyte on the surface of the mixed depolarizer next to the separator, characterized in that the mixed depolarizer is stable in the potassium hydroxide electrolyte and because the battery has a maximum open circuit voltage of approximately 1.75 volts, a single plateau of voltage during discharge and because it is capable of providing an instantaneous current greater than an average of 0.2 amps per cm2 of the area in cross section of the pile.
