Abstract
An electrochemical cell incorporating cathode materials comprising at least one metal oxide, a first metal and a second metal or a mixture of a first and a second metals or their metal oxides incorporated in the matrix of a host metal oxide is described. The cathode materials of this invention are constructed of the chemical addition, reaction, or otherwise intimate contact of various metal oxides and/or metal elements during thermal treatment in mixed states. The materials thereby produced contain metals and oxides of Group IB, IIB, IIIB, IVB, VB, VIB, VIIB, and VIII, which include the noble metals and/or their metal oxide compounds. A preferred material comprises a composite metal oxide matrix formed as the thermal decomposition and reaction product of a matrix of vanadium oxide and at least two decomposable metals including copper and silver.
