Abstract
An alkaline battery having a divalent silver oxide (AgO) positive active material (cathode) in which a sulfide additive is incorporated into the alkaline electrolyte on the positive side of the battery separator or barrier or is added to the positive active material is provided. The sulfide additive improves the stability of the divalent silver oxide (AgO) active material in the aqueous alkaline electrolyte without adversely affecting the electrochemical reaction during the discharge of the battery. The additive consists of a sulfide of cadmium, calcium, mercury, tin, tungsten, or mixtures thereof.
