Abstract: The invention relates to a mixture comprising: —more than 50 to 99% by weight of a lithium phosphate of manganese and iron—1 to less than 50% by weight of at least one lithium oxide of nickel, manganese and cobalt or at least one lithium oxide of nickel, cobalt and aluminium, or of a mixture of these two oxides, these two lithium oxides being rich in nickel. This mixture can be used as active material of the cathode of a lithium-ion electrochemical element. The charging profile of the element has a plateau indicating the end of charging.
