Abstract:
1. A process for the preparation of a mixture comprising at least one compound according to general formula (I) wherein M M M a: 1.5-4.5, b: 0-0.6, c: 0-1.98 and x: number to equalize the charge of Li and V and M wherein a-b is >0, and at least one electrically conducting material, said process comprising (D) providing an essentially aqueous mixture comprising at least one electrically conducting material, and as substrates at least one lithium-containing compound, at least one vanadium-containing compound in which vanadium has the oxidation state +5 and/or +4, and at least one M (E) drying the mixture provided in (D), in order to obtain a solid compound and (F) calcining the solid compound obtained from (E) at a temperature of 300 to 950° C., wherein at least one of the substrates generates at least one gaseous compound and/or at least one precursor of a gaseous compound and the at least one gaseous compound and/or the gaseous compound generated from the at least one precursor of a gaseous compound is liberated in (E) and/or (F).
