Definitions
- the field of use of the present invention relates to the storage of electrical energy, and more particularly to lithium-ion batteries.
- a lithium-ion battery typically includes the following assembly:
- a positive electrode comprising a lithium-based material, a lithium salt-based electrolyte
- a negative electrode (anode), generally based on carbon, for example graphite.
- JP 2013-206746 discloses the material Li 2 NiSii_ x Ti x 0 4 with 0 ⁇ x ⁇ l whose capacity is 120 mAh / g at C / 20 between 4V and 2V,
- the present invention relates to an electrode material of formula Li 2 + x Ni u Ti v Nb w 0 4 in which:
- the formula above comprises at least one of the following parameters:
- the material of formula Li 2 + x Ni u Ti v Nb w 04 is particularly suitable for use as a cathode material, in particular in a lithium-ion battery.
- the material according to the invention may be in the form of particles or agglomerates of particles.
- it is formed of agglomerates of 1 to 5 microns made of particles.
- the particles are preferentially spherical. Their average diameter is advantageously between 30 and 100 nanometers.
- the material is washed with distilled water to remove the salt mixture and then dried at 80 ° C. in air.
- the electrode thus produced is introduced into a cell type "button cell” format 2032.
- the negative electrode is made of lithium metal.
- Two types of separators are used: a polypropylene film (Celgard 2400) and a polyolefin film (Viledon ® ).
