1. A process for producing an active cathode material comprising at least one oxide of a metal M and at least one sulfide of said metal M, comprising
(a) preparing a mixture comprising
(A) at least one liquid organic phase comprising
(A1) at least one organic compound comprising oxygen, and(A2) at least one organic compound comprising sulfur,and(B) at least one source of metal M which is at least partly soluble in the liquid organic phase (A), (b) thermally-treating the mixture formed in (a) at a temperature ranging from 20° C. to 300° C., and, optionally, (c) isolating the active cathode material, which is formed in (b).
