Abstract
Divalent silver oxide (AgO) cathode materials discharge at virtually single voltages, even at low drains. The AgO cathode materials, which comprise AgO, Ag.sub.2 O and silver plumbates (Ag.sub.5 PbO.sub.6 and Ag.sub.2 PbO.sub.2), are the reaction products of minor amount of PbS and major amounts of AgO in hot aqueous sodium hydroxide. Cells incorporating such cathodic materials are thermally stable and exhibit low impedance.
