ABSTRACT:
A method of synthesizing higher surface area vanadium oxides, having the chemical formula V.sub.2 O.sub.13+x, wherein 0.ltoreq.X.ltoreq.0.5, that are employed in fabricating cathode active materials for solid secondary electrochemical cells, is provided. The method includes forming dense NH.sub.4 VO.sub.3 pellets and heating the pellets to decompose the NH.sub.4 VO.sub.3 into V.sub.2 O.sub.5 and NH.sub.3, whereby the NH.sub.3 reduces the V.sub.2 O.sub.5 into vanadium oxides.
