Kind Code:
A
Abstract:
The present invention relates to a Process for the preparation of compounds of general formula (I), Lia-bM1bFe1-cM2cPd-eM3eOx, wherein M1, M2, M3, a, b, c, d and e: M1: Na, K, Rb and/or Cs, M2: Mn, Mg, Ca, Ti, Co, Ni, Cr, V, M3: Si, S, a: 0.8-1.9, b: 0-0.3, c: 0-0.9, d: 0.8-1.9, e: 0-0.5, x: 1.0-8, depending on the amount and oxidation state of Li, M1, Fe, M2, P, M3, wherein compounds of general formula (I) are neutrally charged, comprising the following steps (A) providing a mixture comprising at least one lithium-comprising compound, at least one iron-comprising compound, in which iron has the oxidation state +3, and at least one M1-comprising compound, if present, and/or at least one M2-comprising compound, if present, and/or least one M3-comprising compound, if present, and at least one reducing agent which is oxidized to at least one compound comprising at least one phosphorous atom in oxidation state +5, (B) optionally drying the mixture provided in step (A), in order to obtain a solid compound and (C) calcining the solid compound obtained from step (A) or (B) at a temperature of 300 to 1000° C.
