Abstract:
The present invention relates to a process for the synthesis of a carbon-deposited alkali metal oxyanion cathode material comprising particles, wherein said particles carry, on at least a portion of the particle surface, carbon deposited by pyrolysis, said process comprising a dry high-energy milling step performed on precursors of said carbon-deposited alkali metal oxyanion prior to a solid-state thermal reaction.
