Definitions
- the invention relates to the general field of lithium-ion rechargeable batteries.
- the invention relates to rechargeable lithium - ion batteries comprising a lithium rich positive electrode material and a graphite - based negative electrode material.
- the Li-ion batteries comprise one or more positive electrode (s), one or more negative electrode (s), an electrolyte and a separator composed of a porous polymer or any other suitable material so to avoid any direct contact between the electrodes.
- the LTO material is generally used as a nanoscale material to achieve high lithium intercalation / deintercalation kinetics. High power applications are thus appropriate but the associated cost is high.
- graphite is used as a micron or submicron size material and is generally less expensive than the LTO material.
- FIG. 3 also shows a scanning electron microscope micrograph of a lithium-rich material for a positive electrode
- the lithium-rich positive electrode material may further comprise one or more binders.
- the graphite negative electrode material may further comprise one or more binders as for the positive electrode.
- the binders described above for the positive electrode can be used for the negative electrode.
- the Li-ion battery according to the invention also comprises an electrolyte, preferably a liquid.
- the lithium salt or salts generally comprise inert anions.
- Suitable lithium salts may be selected from lithium bis [(trifluoromethyl) sulfonyl] imide (LiN (CF 3 S 0 2 ) 2 ), lithium trifluoromethanesulfonate (LiCF 3 SO 3 ), bis (oxalato) borate lithium (LiBOB), lithium difluoro (oxolato) borate (LiDFOB), lithium bis (perfluoroethylsulfonyl) imide (LiN (CF 3 CF 2 SiO 2 ) 2 ), LiClO 4 , LiAsF 6 , LiPF 6 , LiBF 4, Lil, LiCH 3 S0 3, LiB (C 2 0 4) 2, LiR F SOSR F, LiN (R F S 0 2) 2, liC (R F S0 2) 3, R F is a group selected from fluorine atom and a perfluoroalkyl group having between one and

- aprotic polar solvents for example ethylene carbonate (denoted “EC”), propylene carbonate, dimethyl carbonate, diethyl carbonate (denoted “DEC”) and methyl and ethyl carbonate.
- the invention also relates to a method for preparing Li-ion batteries according to the invention, comprising the following steps:
- L denotes the density of active material for the negative electrode (mg / cm);
- L denotes the density of active material for the positive electrode (mg / cm 2 );
- Q rev.spe designates the specific reversible capacitance of the positive electrode (mAh / mg),
- a method for preparing Li-ion batteries according to the invention comprises the following steps:
- the cycles being carried out at a capacity of between C / 20 and C, C denoting the capacity of the Li-ion battery.
- the following charging and discharging cycles occur at a capacitance of C / 2.
- a high voltage is used during the activation cycle.
- This "overvoltage” can be likened to an additional capacity of the lithium-rich positive electrode material.
- Said material is used as a “sacrificed lithium” material in this step to form SEI ("Solid Electrolyte Interphase") on the graphite-based negative electrode active material.
- An active material for lithium rich positive electrode is provided by Umicore and has the formula Lii i2 Mno, 5Nio, 2Coo, i 0 2.

- Figures 2 and 3 show snapshots with a scanning electron microscope of the positive electrode thus manufactured. Preparation of the negative electrode
- Active graphite material is provided by Hitachi (SMGHE2). Two types of electrode are prepared, one for comparison and one according to the invention, by mixing 96% by weight of graphite, 2% by weight of carboxyl methyl cellulose (CMC) and 2% by weight of Styrofan latex, c. that is, a carboxylated styrene-butadiene copolymer.
- CMC carboxyl methyl cellulose
- Styrofan latex c. that is, a carboxylated styrene-butadiene copolymer.
- the resulting mixture is respectively deposited on a copper sheet 15 ⁇ thick and then dried and compressed by calendering at 80 ° C.
