ABSTRACT:
Solid divalent silver oxide is reacted in hot aqueous alkaline reaction medium with a solid bismuth component and a reducing agent. The reaction product comprises a novel compound containing silver, bismuth, and oxygen, which is used in making cathode pellets for use in alkaline electrochemical cells. The cells exhibit low internal impedance and substantially single voltage discharge characteristic of monovalent silver oxide while retaining a significant portion of the coulombic capacity a of divalent silver cathode, without toxicity problems attendant cathodes containing lead and/or cadmium.
