The present invention is directed to a method for making electrode active materials represented by the general formula: <?in-line-formulae description="In-line Formulae" end="lead"?>A<SUB>a</SUB>(VO)<SUB>b</SUB>XO<SUB>4</SUB>, <?in-line-formulae description="In-line Formulae" end="tail"?> wherein: (a) A is an alkali metal or mixture of alkali metals, and 0<a<4; (b) 0<b<2; (c) X is selected from the group consisting of phosphorous (P), sulfur (S), arsenic (As), silicon (Si), and combinations thereof; and wherein A, X, a and b are selected to maintain the electroneutrality of the electrode active material in its nascent (as prepared or synthesized) state.
