The subject of the present invention is an electrochemically active electrochemically active material for a lithium rechargeable electrochemical generator comprising a mixture of (I) a mixed oxide of lithium and at least one transition metal of general formula Lix M1y O2y where 0 ≤ x ≤ 1 and y = 1 or 2, with (II) a mixed oxide of phosphorus, of lithium, and of at least one transition metal of general formula M2z PO4 where 0 ≤ x ≤ 3 and z = 1 or 2. The proportion of the mixed oxide of phosphorus, of lithium, and of at least one transition metal is between 1% and 50% by weight of the mixture. Preferably M1 is at least one element chosen from Ni, Co and Mn. and M2 is at least one element selected from Fe, Ni, Co, Mn and V. |
