Abstract
A silver oxide powder for use in the cathode of an alkaline silver oxide galvanic cell, being a mixture of at least 10% divalent silver oxide powder together with monovalent silver oxide powder, is produced by at least partially reducing the silver oxide powder mixture by reacting it with a surfactant, particularly an anionic surfactant and thereafter removing the reactant. The silver oxide powder displays a lower oxygen evolution rate when immersed in an alkaline electrolyte, and lower internal friction during powder flow under pressure when compared with a similar silver oxide mixture which is known not to have been so reacted.
