Abstract:
An electrochemical cell comprising an alkali metal anode; a cathode; and a nonaqueous electrolyte operatively associated with the anode and the cathode, the improvement in the cell comprising:the cathode comprising silver vanadium oxide characterized as having been produced from a first silver constituent selected from the group consisting of AgNO3, AgNO2, Ag2O, Ag2CO3, Ag(CH3CO2), AgVO3, elemental silver, and mixtures thereof and a vanadium oxide as a second constituent, wherein a mixture of the first and second constituents is heated to a first temperature about 2Â° C. to about 40Â° C. above a decomposition temperature of the mixture, followed by grinding and wherein the mixture is then heated to a second temperature about 50Â° C. to about 250Â° C. above the decomposition temperature of the mixture.
