摘要：The invention relates to a material C-AxM(XO4)y that consists of particles of a compound of the formula AxM(XO4)y, wherein said particles comprise a carbon deposit deposited by means of pyrolysis on at least a portion of the surface thereof, and where: A is Li alone or partially replaced by at most 10 atomic % of Na or K; M is Fe(II), or ?n(II), or mixtures thereof alone or partially replaced by at most 30 atomic % of one or more metals selected from Mn, Ni and Co and/or at most 5 % of Fe(III); XO4 is PO4 alone or partially replaced by at most 10 molar % of at least one group selected from SO4, Si04 and MoO4; and where said material has a calcium impurity content of lower than about 1000 ppm.
