Abstract:
1. A method for making a compound represented by the general formula: wherein: (a) A is an alkali metal or mixture of alkali metals and 0<a≦2; (b) X is selected from the group consisting of phosphorous (P), sulfur (S), arsenic (As), silicon (Si), and combinations thereof; and (c) A, X, a and b are selected to maintain the electroneutrality of the compound; the method comprising the steps of: forming an acidic aqueous solution comprising vanadyl ions, ions of an alkali metal, and ions of XO wherein the step of forming the acidic aqueous solution comprises the step of dissolving one or more vanadyl precursor compound, one or more alkali metal precursor compounds, and one or more precursor compounds containing moiety XO precipitating the compound from the acidic aqueous solution.
