Definitions
- the present invention relates to a method of chemically modifying a lithiated oxide comprising at least one lithiated transition metal, said lithiated oxide being advantageously used as an electrode active material, and more particularly as a positive electrode active material for lithium battery.
- the invention also relates to a positive electrode for a lithium battery, comprising such a material.
- the invention finally relates to lithium batteries comprising a positive electrode comprising such a material.
- the general field of the invention is therefore that of lithium batteries.
- Lithium accumulators have been the subject of many developments because of their good results obtained in terms of voltage, mass and volume energy densities, compared to lead accumulators or even nickel - cadmium (Ni - Cd) batteries. ) or Nickel-Metal Hydride (Ni-MH).
- lithium batteries find their application in many fields, particularly in the power supply of low-level embedded systems. thick, such as credit cards, smart labels, in the power supply of mobile phones or in the power supply of electric vehicles.
- Lithium batteries operate on the principle of insertion-deinsertion (or intercalation-deintercalation) of lithium on at least one electrode. More precisely, at each charge or discharge of the accumulator, lithium in ionic form (Li + ) is exchanged between the positive and negative electrodes. The amount of energy exchanged (supplied by the accumulator in discharge or supplied to the charging accumulator) at each charge or discharge is exactly proportional to the amount of lithium that can be exchanged during the electrochemical reaction. .
- Positive electrode active materials are generally lithium oxide ceramics, such as LiCoO 2 , LiNiO 2 and LiMn 2 O 4, or even more complex oxides such as LiNi 0 , sMni, 5 O 4 .
- the insertion-deinsertion phenomenon of lithium in these materials occurs at operating potentials with respect to lithium metal of the order of 4 V or more. In this range of potential, an oxidation of the organic electrolyte with which the positive electrode active material is in contact has been observed, all the more so as the contact surface between the material and the electrolyte is important. This oxidation phenomenon leads to a limited lifetime of the accumulator and in particular a decrease in the discharge capacity after a certain number of charge - discharge cycles of the accumulator.
- the first alternative may be to reduce the surface area of the active material by increasing the particle size of said material.
- this alternative is not interesting, insofar as it can lead to a reduction in the capacities delivered by the accumulator, in particular for high current densities applied.
- a second alternative may be to minimize the direct contact between the particles of active material and the electrolyte, by developing a protective interface between said particles and the electrolyte.
- the inventors have discovered, surprisingly, that by applying a specific treatment to the active material of the positive electrode, the accumulators incorporating the material thus treated have a stability of their discharge capacities as a function of the number of charge-discharge cycles. .
- the object of the invention is therefore to provide a method for chemically modifying a lithiated oxide comprising at least one transition metal that can be used as active material for a positive electrode, which makes it possible to obtain an oxide capable of limiting the phenomenon of oxidation of the electrolyte with which it is in contact.
- the process of the invention differs from prior art processes in that it consists of a chemical modification of the metal oxide of the transition and not a simple deposit on this oxide, as is the case of the prior art.

- the contacting is preferably carried out with stirring for a period of time ranging from 15 minutes to 4 weeks, preferably from 12 hours to 48 hours.
- the aqueous solution comprising phosphate ions may be a solution of lithium dihydrogenphosphate (LiH 2 PO 4 ), a solution of diammonium hydrogenphosphate ((NH 4 ) 2HPO 4 ).
- the aqueous solution may comprise a phosphate ion concentration ranging from 0.025 to 1 mol / l, for example equal to 0.1 mol / l.
- This contacting step can be carried out under heating, for example at a temperature of up to 70 ° C.
- the lithiated oxide comprising at least one transition metal advantageously comprises nickel, manganese, iron, copper, chromium and / or cobalt and optionally one or more elements chosen from Na, Ca, Sr, K, Mg, Nb, Al, Zr, V, Zn, Si, Mo and Ti.
- the oxides that may be used in the context of this process may be chosen in particular from LiCoO 2 , LiMn 2 O 4 , LiNi O , sMni, 5 O 4 .
- a particularly interesting oxide is LiNi 0 , sMni, 5 O 4 .
- the oxides used in the contacting step may be commercially available but may also be prepared beforehand.
- the techniques for preparing such oxides are well known to those skilled in the art.
- One of the known preparation techniques is the sol-gel technique as described in Electrochemica Acta 48 (2003) 503-506.
