    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.

    Abstract translation: 具有二价氧化银（AgO）正极活性物质（阴极）的碱性电池，其中金离子被引入到电池隔板或屏障的正极侧的碱性电解质中或添加到正极活性物质中。 金添加剂改善了碱性电解液中二价氧化银（AgO）活性物质的稳定性，而不会对电池放电期间的电化学反应产生不利影响。 在二价氧化银正极活性物质中，添加剂以约0.1至约10重量％的银的量存在于电池中。 优选二价氧化银活性物质含有至少50重量％的二价氧化银（AgO），剩余的活性物质包含一价氧化银（Ag 2 O）和金属银。 金添加剂可以与其他添加剂组合，并且已经发现在与汞组合时在一些电池中特别有效并且并入正极活性材料或隔膜正极上的电解质中。
