摘要
A method of synthesis of a metal fluorophosphate having the following general formula (1): XaMb(PO4)cFd (1), in which: X is an alkaline metal selected among sodium (Na) and lithium (Li) or a mixture of said metals; M is a transition metal selected among the following elements: Co, Ni, Fe, Mn, V, Cu, Ti, Al, Cr, Mo, Nb or a combination of at least two of said metals, 0@a@5; 0.5@b@3; 0.5@c@3; and d is an integer equal to 1, 2 or 3. The method contains an electric-field-activated sintering process for a mixture (1) formed by at least one first phosphate-containing solid precursor and at least one second fluorine-containing solid precursor.
