Abstract
A single phase silver vanadium oxide prepared from a mixture of a decomposable silver salt and vanadium oxide first heated at about 2° C. to about 40° C. above the decomposition temperature of the mixture followed by a second heating in a temperature range of about 490° C. to about 520° C. is described. The silver vanadium oxide material is coupled with a lithium anode and activated with a nonaquecus electrolyte to provide an improved high energy density electrochemical cell having increased pulse voltages and a reduction in voltage delay.
