Coating and lithiation of inorganic oxidants by reaction with lithiated reductants

A method for producing conductive carbon coated particles of an at least partially lithiated electroactive core material comprises the step of premixing an oxidant electroactive material with a metallated reductant followed by chemically reacting the oxidant electroactive material with the metallated reductant, said reductant being a coating precursor, said metal being at least one alkaline and/or at least one alkaline earth metal, and said chemically reacting being performed under conditions allowing reduction and metallation of the electroactive material via insertion/intercalation of the alkaline metal cation(s) and/or the alkaline earth metal cation(s) and coating formation via a polymerisation reaction like polyanionic or radicalic polymerisation of the reductant.
