ABSTRACT:
The current invention provides a method of preparing a cathode material in a sequential two-part reaction process. In the first step, silver nitrate and vanadium oxide are decomposed by heat under an inert atmosphere. In the second part of the process, the resulting intermediate material is heat treated under an oxidizing atmosphere. The sequential combination of steps produces a highly crystalline silver vanadium oxide cathode material which has properties not heretofore exhibited by SVO prepared by prior art methods.
