Definitions
- the present invention relates to lithium batteries, accumulators or batteries, and more particularly to an active material for the rechargeable battery negative electrode.
- Li-ion type batteries are intended for new applications (portable electronics, wireless tools, hybrid vehicles) that always require more power and energy to meet the needs. They must be stable with long cycle and calendar life. Finally, they must meet societal requirements related to safety and the protection of the environment.
- Graphite is commonly used as a negative electrode for Li-ion batteries.
- lithium titanate oxide ramsdellite, Li 2 Ti 3 O 7
- Such a negative electrode material operates at a voltage higher than that of carbon (> 1V), thus ensuring better operational safety.
- it is less subject to polarization, that is to say the difference between potential charge and discharge, that the graphite and is therefore suitable for use requiring high power.
- the capacity of this material is however relatively low, reaching about 130 Ah / kg at low speed (C / 15) and 100 Ah / kg at high speed (1 C), but has the advantage of having excellent reversibility during fast cycling.
- the reversible capacity at low speed can now reach 140 Ah / kg, thanks to an additional substitution by one or two of the following elements: Ti 3+ ,
- the present invention proposes to further improve the substituted ramsdellite, so as to obtain an improved specific capacity, while preserving the other qualities of the existing poly-substituted product.
- the present invention specifically relates to a negative electrode material that meets the aforementioned needs.
- the invention relates to an active material for lithium battery electrode comprising a phase having the general formula Li 2 + v -4 cCcTi 3 -WFe x MyM ' z O 7 - ⁇ , in which M and M 1 are metal ions groups 2 to 15 having an ionic radius between 0.5 and 0.8 ⁇ in octahedral oxygen environment, v, w, x, y, z and ⁇ being linked by the relationships:
- the M and M 'ions can be selected from the list composed of Ti 3+ , Co 2+ , Co 3+ , Ni 2+ , Ni 3+ Cu 2+ , Mg 2+ , Al 3+ , In 3+ , Sn 4+ , Sb 3+ , and Sb 5+ .
- M is preferably Ni 2+ and M 'of Al 3+ .
- Another subject of the invention relates to a process for synthesizing the active material defined above, and comprising the steps of:
- the cooling of the ceramic phase is at least 100 ° C / min, from the synthesis temperature to less than 400 ° C.
- the invention also relates to the use of the active material defined above for the manufacture of batteries, accumulators or lithium batteries.
- the invention finally also relates to batteries, accumulators or lithium batteries comprising the active material defined above.
- the material of the invention has mass and volume capacities of up to 190 Ah / kg, ie 602 Ah / m 3 , ie higher than those of the state of the art, while retaining the previously acquired advantages. , especially:
- the ramsdellite structure consists of a network comprising Ti and Li atoms in an octahedral environment of oxygen and channels partially occupied by Li atoms in a tetrahedral environment. This arrangement leaves a large number of vacant tetrahedral sites in the channels and the Li / gap distribution can vary depending on the synthesis conditions.
- the substitution metals occupy the octahedral sites of the network.
- the first step of the process according to the invention comprises a reactive mixture of compounds.
- Solid precursors in the form of fine powder, are selected and mixed.
- This mixture preferably comprises oxides of Ti and Fe, as well as those of metals M and M '.
- Other precursors are also suitable, these being organic and / or inorganic compounds capable of forming Me-O-Me bonds (where Me is a metal) by condensation or hydrolysis / condensation.
- oxides, carbonates, acetates, hydroxides, chlorides (eg AlCl 3 ), nitrates, Me-oxoalkoxides this list not being exhaustive and the man of the profession will be able to complete it.
- As for lithium it may be provided by another precursor, such as an oxide, hydroxide, or chloride. Li 2 CO 3 is however preferred.
- the mixture will also comprise carbon or carbon precursors which will be the simplest hydrocarbon phases such as monosaccharides or monosaccharides, for example glucose, fructose, sucrose, ascorbic acid, and polysaccharides corresponding to the condensation of monosaccharides. as starch, cellulose and glycogen.
- carbon or carbon precursors which will be the simplest hydrocarbon phases such as monosaccharides or monosaccharides, for example glucose, fructose, sucrose, ascorbic acid, and polysaccharides corresponding to the condensation of monosaccharides. as starch, cellulose and glycogen.
- the proportion of each of the metals in the precursor mixture corresponds to the stoichiometric proportion of the target material, leading to the formation of the composite.
- the proportion of carbon will be calculated taking into account the losses of CO and CO 2 by oxidation. This proportion may be increased if excess grain is desired at the grain boundaries.
- the second step of the process according to the invention comprises a heat treatment.
- the heat treatment is carried out under a controlled atmosphere (eg N 2 , Ar); it is carried out at a temperature which can be between 980 ° C and 1050 ° C, preferably between 1:30 and 2 h, to obtain good crystallinity, correlated with a limited particle size.
- a controlled atmosphere eg N 2 , Ar
- the rise in temperature to reach the reaction stage can be carried out in a single fast step because it makes it possible to minimize side reactions and the formation of undesirable titanates.
- the last step is to cool the material quickly.
- the manufacturing process as a whole is fast and has a reduced implementation cost.

- the heat treatment is performed in nacelle under Ar one step. A ramp of 7 ° C / min is applied up to a synthesis temperature of 980 ° C, this temperature being maintained for 1h30.
- the cooling is carried out rapidly, under argon, so as to freeze the high temperature structure.
- Sucrose is added as carbon precursor, representing 5, 10 and 15% by mass relative to the total weight weighed before synthesis. Refer to Table 1 for different carbon levels.
- a reagent grinding of the compounds Li 2 CO 3, TiO 2 anatase nanosized, Fe 2 O 3, NiO, Al 2 O 3 in stoichiometric amounts, and sucrose is carried out in a Pulverisette ® 7 (duration 15 min; rate 8) with agate balls and a bead / mass mass ratio of product equal to 10.
- the heat treatment is carried out as in Example 1.
- Figure 1 shows the photos of scanning microscopy of the various synthesized examples.
- the IR spectra of FIG. 2 show (bd) for the products prepared according to examples 2 to 4, the presence of vibration bands between 1430 and 1500 cm -1 , characteristic of the CO 3 2 "group . This confirms the substitution of carbon in the ramsdellite structure.
- the product prepared according to Example 4 shows (d) also vibration bands at about 1650 cm -1, which correspond to the conjugated CC bonds which belong to the surface carbon.
- the electrochemical tests are performed in a half-cell with two electrodes, the negative of which is a lithium metal washer.
- the positive comprises a mixture of 85% by weight of active material, 5% by weight of carbon black and 10% by weight of PTFE binder.
- the electrolyte used is LiPF 6 (1 M) in ethylene carbonate, dimethyl carbonate and propylene carbonate (1: 3: 1).
- the cycling is carried out in galvanostatic mode at 25 ° C between 1 and 2.5 V vs. Li / Li + at diets of C / 15 and 1 C.
- FIG. 3 (a) shows the charge and discharge (vs. Li) curves of the carbon-free material, prepared according to example 1.
- FIG. 3 (b) corresponds to the material with carbon, according to example 3. These measurements are performed in galvanostatic mode at a C / 15 rate between 1 and 2.5 V vs Li / Li + .
- the observed capacity for the carbon-free material is 130 Ah / kg.
- the curve shows a shoulder between 1.4 and 2.5 V. Thanks to the carbon, the values of the reversible capacities are improved, reaching here 180 Ah / kg, with a low irreversible capacity of 8 Ah / kg, and a low polarization of 67 mV.
