Producing electrode material, comprises (a) mixing (A) at least one phosphorus compound, (B) at least one lithium compound, (C) at least one carbon source, (D1) at least one water-soluble iron compound in which iron is present in +2 or +3 oxidation state, and (D2) at least one iron source different from the component (D1), in which iron is present in 0, +2 or +3 oxidation state, and which is insoluble in water, and (b) thermally treating the obtained mixture. An independent claim is also included for an electrode material, preferably a mold, comprising agglomerates of primary particles, which comprise (i) primary particles of lithiated iron phosphate with olivine structure, exhibiting an average diameter of 20-250 nm, (ii) primary particles of lithiated iron phosphate with olivine structure, exhibiting an average diameter of 300-1000 nm, and (iii) optionally carbon in electrically conductive modification. |
