Abstract
An alkali metal oxyanion cathode material comprising particles, where the particles carry, on at least a portion of the particle surface, carbon deposit by pyrolysis is described. The particles have the general formula A:M:M′:XO4 where the average valency of M is +2 or greater; A is at least one alkali metal selected from Li, Na and K; M is at least Fe and/or Mn; and M′ is a metal of valency of 2+ or more.
