Abstract (en)

[origin: WO2006057146A2] An object of the present invention is to provide a method of more efficiently producing an electrode active material whose main component is a transition metal phosphate compound. According to the present invention, a method of producing an electrode active material is provided in which the main component thereof is a phosphate compound represented by the general formula: A<SUB>x</SUB>M(PO<SUB>4</SUB>) <SUB>y</SUB> (here, 0 = x = 2, 0 < y = 2, A is an alkali metal, and M is a transition metal). This method comprises preparing a composition in the melted state that contains a source of M and a source of phosphorus (and also a source of A when 0 < x). This method is suitable as a method of producing an electrode active material whose main component is, for example, an olivine-type lithium iron phosphate compound.
