A method for preparing a NaV(PO)Fmaterial, including at least the steps: a) reducing the vanadium oxide, VO, under a reducing atmosphere in the absence of elementary carbon and in the presence of at least one phosphate anion precursor in order to form vanadium phosphate, VPO; and b) exposing, under an inert atmosphere, a mixture of the VPOmaterial obtained in step a) with an effective amount of sodium fluoride, NaF, and at least one hydrocarbon- and oxygen-containing compound which is a source of elementary carbon, to temperature conditions that are favourable for calcining said mixture so as to form said NaV(PO)Fcompound. Also, a related electrode material, an electrode and a secondary sodium battery using the presented material.
