Patent ES-429503-A1 (ES)
Title: Additive for an alkaline battery employing divalent silver oxide positive active material
IPC: H01M6/06
Filed: 1974-08-01
Abstract: An alkaline battery having a divalent silver oxide (AgO) positive active material (cathode) in which gold ions are incorporated into the alkaline electrolyte on the positive side of the battery separator or barrier or added to the positive active material. The gold additive improves the stability of the divalent silver oxide (AgO) active material in the aqueous alkaline electrolyte without adversely affecting the electrochemical reactions during the discharge of the battery. The additive is present in the battery in amounts ranging from about 0.1 to about 10% by weight of silver in the divalent silver oxide positive active material. It is preferred that the divalent silver oxide active material contain at least 50% by weight of divalent silver oxide (AgO) with the balance of the active material comprising monovalent silver oxide (Ag2O) and metallic silver. The gold additive may be combined with other additives and has been found to be particularly effective in some batteries when combined with mercury and incorporated into either the positive active material or the electrolyte on the positive side of the separator.
