| 摘要 |
The present invention is directed to a process for preparing a cathode active material consisting of a single phase of mixed metal oxide, such as a single phase silver vanadium oxide. The synthesis technique involves first heating the starting materials to melt a decomposable starting constituent. This first heating temperature is held for a period of time sufficient to enable the decomposable starting constituent to melt and completely flow throughout and within the other starting materials. Then, the thusly produced melt impregnated reaction admixture is preferably ground to ensure complete homogeneity of the starting materials, followed by heating to the decomposition temperature of the decomposable starting constituent. To finish the synthesis, the decomposed admixture is heated to an elevated temperature above the decomposition temperature to provide the single phase mixed metal oxide.
