Abstract
The present invention relates to a process for the preparation of particles comprising at least one compound according to general formula (I) MaMbMcOoNnFf (I) wherein M, M, MO, N, F, a, b, c, o, n and f have the following meanings: M1 at least one alkaline metal, M2 at least one transition metal in oxidation state +2, M3 at least one non-metal chosen form S, Se, P, As, Si, Ge and/or B, O oxygen, N nitrogen, F fluorine, a 0.8-4.2, b 0.8-1.9, c 0.8-2.2, o 1.0-8.4, n 0-2.0 and f 0-2.0, wherein a, b, c, o, n and f are chosen to ensure electroneutrality of the compound according to general formula (I), and carbon, comprising at least the following steps: (A) providing an essentially aqueous mixture comprising at least one compound comprising M, at least one compound comprising Mhaving at least partially an oxidation state higher than +2, optionally at least one compound comprising M, at least one compound comprising N, if present, and/or at least one compound comprising F, if present, at least one polysaccharide comprising glucose having a molecular weight M of at least 50000 g/mol as carbon precursor and at least one reducing agent, (B) drying the mixture provided in step (A), in order to obtain a solid particle and (C) calcining the solid particle obtained from step (B) at a temperature of 300 to 950° C.
