Composition comprises: a lithiated oxide of transition metals containing at least nickel, cobalt and aluminum; and a lithiated phosphate of at least one transition metal, the surface of which is at least partially covered by a layer of carbon, the proportion by mass of the lithiated oxide of transition metals containing at least nickel, cobalt and aluminum, is = 10 wt.% of the composition, and the proportion by mass of the lithiated phosphate of transition metal is >= 90 wt.% of the composition. Independent claims are also included for: (1) an electrode comprising the composition; (2) an accumulator comprising: a non-aqueous electrolyte; at least one negative electrode; and at least one positive electrode; and (3) process for charging the accumulator at a charging current of at least 2 C, where the charged capacity represents at least 150% of the nominal capacity for a cut-off voltage of 3.6 V or at least 140% of the nominal capacity for a cut-off voltage of 4.1 V. |
