Description

[0001]COATING MATERIALS BASED ON FUNCTIONALIZED ORGANIC MOLECULES AND THEIR USES IN ELECTROCHEMICAL APPLICATIONS RELATED APPLICATION The present application claims priority, under applicable law, from Canadian patent application number 3208410 filed on August 4, 2023, the content of which is incorporated herein by reference in its entirety and for all purposes. TECHNICAL FIELD The present application relates to the field of coatings and their use in electrochemical applications. More particularly, the present application relates to coatings for particles of ionically conductive inorganic material, electrochemically active material, electronic conductor, to their manufacturing processes and to their uses in electrochemical cells, in particular in so-called all-solid-state batteries.STATE OF THE ART All-solid-state electrochemical systems are substantially safer, lighter, more flexible, and more efficient than their counterparts based on the use of liquid electrolytes. However, the scope of application of solid electrolytes is still limited. Indeed, solid polymer electrolytes present problems related to their limited electrochemical stability, their low transport number, and their relatively low ionic conductivity at room temperature. Ceramic-based solid electrolytes exhibit a wide window of electrochemical stability and a substantially higher ionic conductivity at room temperature. However, they are associated with problems related to their interfacial stability as well as their stability in ambient air and humidity.Some ceramics, such as those based on sulfides, can also react with other battery constituents, such as those in the electrode, thereby reducing battery life. Furthermore, the manufacture of solid electrolytes and electrode materials for all-solid-state electrochemical systems also frequently encounters dispersion problems, particularly when forming composite electrodes and electrolytes. More specifically, because the nature of the elements in a composite, for example, polymers and inorganic particles, is different, solid elements may tend to form agglomerates within a polymer matrix or electrode binder, which may adversely affect the performance, efficiency, or stability of the system.These dispersion problems can also be significantly reduced through the use of binders, additives or dispersion media resulting in better particle dispersion. Examples of dispersion media are described in the European patent published under number EP 3467845, these being present in the composition of the solid electrolyte. Other examples are also described in the international patent application WO2022 / 251968. The manufacture of ceramic-based solid electrolytes is associated with cracking problems following the dry pressing process. One strategy employed to solve this problem involves the encapsulation of the ceramic-based solid electrolyte particles by a substantially flexible (or elastic) polymer.For example, Korean patent publication number KR 10-2003300 describes a polymer coating layer comprising an acrylic-, fluorine-, diene-, silicone-, or cellulose-based polymer applied to the surface of sulfide-based crystalline electrolyte particles. In addition to minimizing the risk of cracking of the solid electrolyte, the polymer coating layer also allows the aggregation of the electrolyte particles without lowering their ionic conductivity and allows for the absorption of volume changes during cycling. Although this strategy achieves attractive properties, it does not address the previously mentioned dispersion issues. Therefore, there is a need for the development of all-solid-state electrochemical systems that exclude one or more of the disadvantages of conventional all-solid-state electrochemical systems.SUMMARY In some aspects, embodiments of the present technology comprise the following items: Item 1.

When the electrolyte is a liquid electrolyte, a gel electrolyte or a solid polymer electrolyte, the coated particles as defined herein may be present as an additive in the electrolyte. When the electrolyte is a polymer-ceramic hybrid solid electrolyte or a ceramic-type solid electrolyte, the coated particles as defined herein may be present as an inorganic solid electrolyte material (e.g., as a ceramic).According to another example, the electrolyte may also optionally include additional components such as ionic conductive materials, inorganic particles, glass or ceramic particles as defined above and other additives of the same type.

According to one example, the additional component may be substantially dispersed in the electrolyte.Alternatively, the additional component may be present in a separate layer. The present technology also relates to a coating material for a current collector comprising coated particles as defined herein, wherein the core of the coated particle comprises an electronically conductive material. For example, the coated particles may be coated conductive carbon particles that may be coated onto a metal current collector foil (e.g., aluminum or copper foil). A current collector comprising the coating material coated onto a metal foil is also contemplated. The present technology also relates to an electrochemical cell comprising a negative electrode, a positive electrode, and an electrolyte, wherein at least one of the positive electrode or the negative electrode is as defined herein or comprises an electrode material as defined herein.According to one variant of interest, the negative electrode is as defined herein or comprises an electrode material as defined herein. For example, the electrochemically active material of the negative electrode may be chosen for its electrochemical compatibility with the various elements of the electrochemical cell as defined herein. For example, the electrochemically active material of the negative electrode material may have a substantially lower oxidation-reduction potential than that of the electrochemically active material of the positive electrode. According to another variant of interest, the positive electrode is as defined herein or comprises an electrode material as defined herein and the negative electrode includes an electrochemically active material selected from all known compatible electrochemically active materials.For example, the electrochemically active material of the negative electrode may be chosen for its electrochemical compatibility with the various elements of the electrochemical cell as defined herein. Non-limiting examples of electrochemically active materials of the negative electrode include alkali metals, alkaline earth metals, alloys comprising at least one alkali or alkaline earth metal, non-alkali and non-alkaline earth metals (e.g., indium (In), germanium (Ge) and bismuth (Bi)), and alloys or intermetallic compounds (e.g., SnSb, TiSnSb, Cu2Sb, AlSb, FeSb2, FeSn2 and CoSn2). For example, the electrochemically active material of the negative electrode may be in the form of a film having a thickness in the range of about 5 µm to about 500 µm and preferably in the range of about 10 µm to about 100 µm, upper and lower limits inclusive.According to a variant of interest, the electrochemically active material of the negative electrode may comprise a film of metallic lithium or of an alloy including or based on metallic lithium. According to another example, the positive electrode may be prelithiated and the negative electrode may be initially (i.e. before cycling of the electrochemical cell) substantially or completely free of lithium. The negative electrode may be lithiated in situ during cycling of said electrochemical cell, in particular during the first charge. According to one example, metallic lithium may be deposited in situ on the current collector (for example, a copper current collector) or on a non-lithiated material during cycling of the electrochemical cell, in particular during the first charge.In another example, an alloy including metallic lithium may be generated on the surface of a current collector (e.g., an aluminum current collector) or other metal during cycling of the electrochemical cell, especially during the first charge. It is understood that the negative electrode may be generated in situ during cycling of the electrochemical cell, especially during the first charge.

The present technology also relates to an electrochemical cell comprising a negative electrode, a positive electrode and an electrolyte, wherein the electrolyte is as defined herein.The present technology also relates to an electrochemical cell comprising a negative electrode, a positive electrode and an electrolyte, wherein at least one of the positive electrode and the negative electrode is on a current collector as defined herein or comprising a coating material as defined herein. The present technology also relates to a battery comprising at least one electrochemical cell as defined herein. For example, the battery may be a primary (cell) or secondary (accumulator) battery. In one example, the battery is selected from the group consisting of a lithium battery, a lithium-ion battery, a sodium battery, a sodium-ion battery, a magnesium battery, a magnesium-ion battery, a potassium battery and a potassium-ion battery. In one variant of interest, the battery is a so-called all-solid-state battery.In another example, the coating material may allow a substantial reduction in the number and size of particle agglomerates in a dispersion. For example, the coating material allows a substantial reduction in the number and size of particle agglomerates of electrochemically active material in an electrode material, of an electronically conductive material in an electrode material or on a current collector, or of an inorganic material in an electrolyte or electrode material. Without wishing to be bound by theory, for example, repulsive interactions related to the coating material may allow a better dispersion of the constituents of the positive electrode in the dispersion, whether or not by modifying the other constituents allowing this type of interaction. For example, the repulsive interactions may be π-π and / or polar interactions.The present coating material may also allow in certain cases the use of solvents usually incompatible with the material included in the core of the coated particle. According to another example, the coating material may also substantially limit parasitic reactions with the other constituents of the electrochemical cell and thus improve the cycling and aging stability of the electrochemical cell. According to another example, the coating material may also substantially limit the charge transfer resistance and may allow substantial improvement of the ionic and / or electronic conductivity thanks to the double or triple bonds present in the coating material. Without wishing to be bound by theory, the π orbitals of the coating material as defined here may allow orbital delocalization and therefore orbital interactions with the ions and / or electrons.In another example, the coating material may also substantially improve the safety of the electrochemical cell, for example, by reducing gas generation. For example, when applied to a particle of sulfide-based ceramic electrolyte material, the coating may substantially reduce the amount of hydrogen sulfide (H2S) generated by exposure of the coated material to moisture or ambient air. In one example, the coating material may also include additional organic compounds or molecules to trap gas molecules (e.g., H2S) and / or to form a barrier to reduce the introduction of moisture to decrease H2S formation.

The particles thus obtained were subsequently dried under vacuum at a temperature of about 80 °C to remove the decane. Table 2. Coated particles a P articules Céramique Volume Volume #Compound (4 g) farnesene squalene (volume) P-5 2 2 mL - 1 (2 mL) P-6 2 2 mL - 2 (2 mL) ygq Thermogravimetric analyses were carried out at a temperature rise rate of 10 °C / min. Thermogravimetric curves of the Li6PS5Cl sulfide solid electrolyte coated with a farnesene – squalene mixture (PA, curve 1), for Li6PS5Cl particles coated with a farnesene – Compound 2 mixture (P-4, curve 2), for Li6PS5Cl particles coated with a Compound 2 – squalene mixture (P-2, curve 3), for Li6PS5Cl particles coated with a farnesene – Compound 1 mixture (P-3, curve 4), for Li6PS5Cl particles coated with a Compound 1 – squalene mixture (P-1, curve 5), as described in Example 2(a) are shown in Figure 1. Figure 1 shows that the coated amount is relatively similar for each of the samples, demonstrating the grafting of Compound 2 or Compound 1.It is noted that when combining Compound 2 or Compound 1 with squalene, the coating is greater than when combining with farnesene, confirming the superior interaction of these new coating molecules of the present invention with sulfides. The thermogravimetric curves of the solid sulfide electrolyte of the type Li5.4PS4.1O0.3ClBr0.5I0.1 coated with a mixture of farnesene – squalene (PB, curve 6), for Li5.4PS4.1O0.3ClBr0.5I0.1 particles coated with a mixture of farnesene – Compound 2 (P-6, curve 7), for Li5.4PS4.1O0.3ClBr0.5I0.1 particles coated with a mixture of farnesene – Compound 1 (P-5, curve 8), and for Li5.4PS4.1O0.3ClBr0.5I0.1 particles coated with Compound 1 only (P-7, curve 9), as described in Example 2(a) are shown in Figure 2. Figure 2 shows that the amount coated is relatively similar for each of the samples in the context of the mixture with farnesene.On the other hand, when coated with Compound 1 alone, the coated quantity is greater, confirming the greater interaction between the sulfides and the organic molecules of the present invention. Thus, the molecules of the present invention make it possible to better coat sulfide-type solid electrolytes, regardless of their composition. Thermogravimetric curves of Li6PS5Cl sulfide solid electrolyte coated with a farnesene – squalene mixture (PA, curve 1), for Li6PS5Cl particles coated with a squalene – Compound 4 mixture (P-9, curve 10), for Li6PS5Cl particles coated with a squalene – Compound 9 mixture (P10, curve 11), as described in Example 2(a) are presented in Figure 3. Figure 3 shows that the coated amount is relatively similar for Compound 4. For Compound 9, a slight decrease in coating is observed but remains in the range of approximately 90% demonstrating coating of each of the samples.By the present invention it is thus possible to mold the coatings but also their chemical nature according to the desired effects. The thermogravimetric curves of the solid sulfide electrolyte of the Li6PS5Cl type coated with a mixture of farnesene – squalene (PA, curve 12) and for Li6PS5Cl particles coated with a mixture of squalene – Compound 15 (P-11, curve 13), as described in Example 2(a) are presented in Figure 4. The thermogravimetric curves of the solid sulfide electrolyte of the Li6PS5Cl type coated with a mixture of farnesene – squalene (PA, curve 12) and for Li6PS5Cl particles coated with a mixture of squalene – Compound 11 (P-12, curve 14) or a mixture of squalene – Compound 12 (P-13, curve 15), as described in Example 2(a) are presented in Figure 5.Thermogravimetric curves of the Li6PS5Cl sulfide solid electrolyte coated with a farnesene–squalene mixture (PA, curve 16) and for Li6PS5Cl particles coated with a squalene–Compound 14 mixture (P-15, curve 17), as described in Example 2(a) are shown in Figure 6. (c) Impedance 10 mm diameter pellets were formed from the powders prepared in Example 2. 160 mg were placed in a 10 mm diameter mold and compressed under a pressure of 2.8 tons using a press. The pellets were then placed in a conductivity cell at a pressure of 5 MPa closed under an inert argon atmosphere. Ionic conductivity measurements of the cells assembled in this example were performed with a VMP-300 multichannel potentiostat (Bio-Logic. MC). The measurements were carried out over a frequency range from 7 MHz to 200 mHz under an amplitude of 50 mV in a temperature interval from -10°C to 70°C in rise (every 10°C) and from 70°C to 20°C in temperature fall (every 10°C). Only the results at 20°C are presented here in Figures 1, 2 and 4 to 6. In Figure 1, the Li6PS5Cl sulfides with coatings resulting from the combination of Compound 1 or Compound 2 with squalene exhibit higher conductivities than with the combination with farnesene for the same coating rate or even higher as previously described in (b). Thus these new coating molecules of the present invention make it possible to maintain a high conductivity of the sulfides while coating them, demonstrating a stronger interaction with the Li6PS5Cl sulfides. In Figure 2, the sulfides Li5.4PS4.1O0.3ClBr0.5I0.1 with coatings resulting from the combination of Compound 1 or Compound 2 with farnesene have higher conductivities for the same coating rate. The ionic conductivity of the sulfide coated with Compound 1 alone has the lowest conductivity, confirming the greater amount of organic molecule coating. This value of 0.33 mS / cm is still interesting because it is greater than 10. -4 S / cm at 20°C. For Figures 4 to 6, the conductivities are in the same order of magnitude with respect to the reference, demonstrating the maintenance of the conduction properties of the powdered sulfide electrolyte thus prepared. (d) NMR spectroscopy Samples of coated particles were analyzed by NMR 1H in the solid state under magic angle rotation (MAS). These spectra were obtained using a Bruker AVANCE NEO 500 MHz WB spectrometer equipped with a 4 mm triple resonance probe with MAS (up to 15 kHz) on the coated particles after drying at 80°C. Figure 7 shows the results obtained with P-4 particles. The NMR spectrum 1 H of P-4 corresponds to the superposition of the previously recorded NMR spectra of farnesene and Compound 2 with the characteristic signals of hydrogens located near the sulfur atom labeled as 1 and 2. There are no signals corresponding to decane in the spectra. We therefore have a combination of farnesene and Compound 2 around the solid electrolyte particles. Figure 8 presents the results obtained with the P-3 particles. The NMR spectrum 1H of P-3 corresponds to the superposition of the NMR spectra of farnesene and Compound 1 recorded previously with the characteristic signals of hydrogens located near the oxygen atom labeled as 1 and 2. There are no signals corresponding to decane in the spectra. We therefore have a combination of farnesene and Compound 1 around the solid electrolyte particles. Figure 9 presents the results obtained with the P-11 particles. The NMR spectrum 1 H of P-11 corresponds to the superposition of the NMR spectra of squalene and Compound 15 recorded previously with the characteristic signals of hydrogens located near the aromatic group labeled as 1, 2 and 3. There are no signals corresponding to decane in the spectra. We therefore have a combination of squalene and Compound 15 around the solid electrolyte particles. Figure 10 presents the results obtained with the P-9 particles. The NMR spectrum 1H of P-9 corresponds to the superposition of the NMR spectra of squalene and Compound 4 recorded previously with the characteristic signals of certain hydrogens labeled 1 to 5. Figure 11 presents the results obtained with P-10 particles. The NMR spectrum 1 H of P-10 corresponds to the superposition of the NMR spectra of squalene and Compound 9 recorded previously with the characteristic signals of certain hydrogens labeled 1 to 6. Figure 12 presents the results obtained with P-12 particles. The NMR spectrum 1 H of P-12 corresponds to the superposition of the NMR spectra of squalene and Compound 11 recorded previously with the characteristic signals of certain hydrogens labeled 1 to 8. Figure 13 presents the results obtained with P-14 particles. The NMR spectrum 1H of P-14 corresponds to the superposition of the NMR spectra of squalene and Compound 3 recorded previously with the characteristic signals of certain hydrogens labeled 1 to 3. Figure 14 presents the results obtained with P-15 particles. The NMR spectrum 1H of P-15 corresponds to the superposition of the NMR spectra of squalene and Compound 14 recorded previously with the characteristic signals of certain hydrogens labeled 1 to 4. Example 3 – Preparation and characterization of positive electrode films a) Preparation of positive electrode films 1.55 g of LiNi0.6Mn0.2Co0.2O2 (NMC 622) particles coated with LiNbO3 type oxide from commercial source having an average diameter of about 4 µm were mixed with 0.40 g of coated PA, PB, P-4, P-5, P-7, P-9, P-10 or P-11 particles (see Table 3) prepared in Example 2 having an average diameter of about 200 nm and 0.5 g of a modified carbon black (CN) mixture as described in the international patent application WO2019 / 218067 and gas-formed carbon fibers (VGCF) to form a dry powder mixture. The dry powders were mixed for approximately 10 minutes using a vortex mixer.A polymer solution was prepared separately by dissolving 0.04 g of polybutadiene and 0.01 g of polynorbornene in 0.94 g of a toluene-tetrahydrofuran mixture (80-20) in the presence of Li6PS5Cl (PA, P-4, P-9, P-10 and P-11) and orthoxylene-diethyl carbonate–tetrahydrofuran (70-20-10) in the presence of Li5.4PS4.1O0.3ClBr0.5I0.1 (PB, P-5, P7). The polymer solution was added to the dry powder mixture. The resulting mixture was mixed for about 5 minutes using a planetary centrifugal mixer (Thinky Mixer). An addition of the previous solvent mixture was made to the mixture to achieve an optimal viscosity for coating, i.e., about 10000 cP. The resulting suspension was coated onto an aluminum foil using a doctor-blade coating method to obtain a positive electrode film applied to a current collector.The positive electrode film was then dried under vacuum at a temperature of about 120°C for about 5 hours. The aluminum foil could also be an unmodified carbon-coated aluminum foil or a carbon-coated aluminum foil coated with the coating material as defined herein. The composition of the positive electrode films is shown in Table 3. Table 3. Composition of the positive electrode films No. l tr d Active material Carbon particles* Binder*** N e ; GNP: po ynorbornene. b) Characterization of the prepared positive electrode films Morphological studies of the different positive electrode films were carried out using a scanning electron microscope (SEM). Figure 15 shows SEM images of the edge of the positive electrode films prepared in Example 3(a) with in (a) the use of the sulfide catholyte Li6PS5Cl coated with squalene – farnesene (F-1) and in (b) a mixture of farnesene – Compound 2 (F-2) as catholyte. It appears that the use of the present invention makes it possible to eliminate the presence of small sulfide agglomerates observed during the squalene-farnesene coating even if this number of agglomerates is already very low. Thus, the coating of the Li6PS5Cl particles by the present invention makes it possible to increase the dispersion of sulfides and considerably limit the presence of agglomerates.Figure 16 shows an SEM image of the sliced ​​positive electrode film prepared in Example 3(a) using the sulfide catholyte Li5.4PS4.1O0.3ClBr0.5I0.1 prepared in Example 5 with the coating of Compound 1 alone (F-5). No agglomerates of sulfide, carbon, or NMC active material are observed. It appears that the use of the present invention eliminates the presence of agglomerates regardless of the material on which it is coated. Example 4 – Electrochemical Properties The electrochemical properties of the positive electrode films prepared in Example 3(a) were investigated. a) Electrochemical Cell Configurations The electrochemical cells were assembled according to the following procedure. 10 mm diameter pellets were taken from the positive electrode films prepared in Example 3(a).Sulfide-based ceramic-type inorganic solid electrolytes were prepared by placing 80 mg of Li6PS5Cl sulfide ceramic on the surface of the positive electrode film pads. The positive electrode film pads including the inorganic solid electrolyte layer were then compressed under a pressure of 2.8 tons using a press. They were then assembled, in a glove box, in CR2032-type coin cell cases facing 10 mm diameter lithium metal electrodes on stainless steel current collectors. The electrochemical cells were assembled according to the configurations shown in Table 4. Table 4. Electrochemical cell configurations Cell Positive electrode film Electrolyte Negative electrode Cell 1 F-1 Li6PS Cl Lithium metal ue. ) comporemen es ce ues en cycage This example illustrates the electrochemical behavior of the electrochemical cells as described in Example 4(a). The electrochemical cells assembled in Example 4(a) were cycled between 4.3 V and 2.5 V vs Li / Li +at a temperature of 30 °C. The formation cycle was carried out at a constant charge and discharge current of C / 15. Then four cycles were carried out at a constant charge and discharge current of C / 10 followed by four cycles at a constant charge and discharge current of C / 5. Finally, the aging experiments were carried out at a constant charge and discharge current of C / 3. Figure 17 shows a plot of discharge and charge capacity (mAh / g) and coulombic efficiency (%) versus cycle number for Cell 1 (open symbols) containing Li6PS5Cl solid sulfide electrolyte of a farnesene – squalene mixture as catholyte and for Cell 2 (solid symbols) containing Li6PS5Cl solid sulfide electrolyte coated with a farnesene – Compound 2 mixture as catholyte as described in Example 4(a).Thus, the coating of the catholyte with farnesene – Compound 2 makes it possible to improve the aging conditions of the positive electrode by reducing its capacity loss in comparison with the coating with the squalene-farnesene mixture. Thus, the contribution of the coating with the new molecules of the present invention makes it possible to improve the electrochemical performances of the battery while reducing the phenomenon of aging and parasitic reaction, reflecting a good coating of our sulfide catholytes and a better interaction with the different components within the positive electrode.Figure 18 shows a plot of discharge and charge capacity (mAh / g) and coulombic efficiency (%) versus cycle number for Cell 1 (open circle symbols) containing Li6PS5Cl sulfide solid electrolyte of a farnesene – squalene mixture as catholyte, for Cell 6 (star symbols) containing Li6PS5Cl sulfide solid electrolyte coated with a squalene – Compound 4 mixture as catholyte and for Cell 7 (hexagonal symbols) containing Li6PS5Cl sulfide solid electrolyte coated with a squalene – Compound 9 mixture as catholyte as described in Example 4(a). Thus, coating the catholyte with squalene – Compound 4 or squalene – Compound 9 greatly improves the aging conditions of the positive electrode by reducing its capacity loss compared to coating with the squalene-farnesene mixture.Thus, the contribution of the coating by the new molecules of the present invention makes it possible to improve the electrochemical performances of the battery while reducing the phenomenon of aging and parasitic reaction, reflecting a good coating of our sulfide catholytes and a better interaction with the different components within the positive electrode. Figure 19 shows, in a graph, the discharge capacity (mAh / g) and the coulombic efficiency (%) as a function of the number of cycles for Cell 3 (square symbols) containing the Li-type sulfide. 5.4 PS 4.1 O 0.3 ClBr 0.5 I 0.1 coated with a mixture of farnesene – squalene as catholyte, for Cell 4 (triangle symbols) containing the Li-type sulfide 5.4 PS 4.1 O 0.3 ClBr 0.5 I 0.1 coated with a mixture of farnesene – Compound 1 as catholyte, and for Cell 5 (round symbols) containing Li-type sulfide5.4 PS 4.1 O 0.3 ClBr 0.5 I 0.1coated with Compound 1 alone as catholyte as described in Example 2 Thus, coating the catholyte Li5.4PS4.1O0.3ClBr0.5I0.1 with farnesene – Compound 1 or Compound 1 alone improves the aging of the positive electrode by reducing its capacity loss compared to coating with the squalene-farnesene mixture. It should be noted that the cyclability with the coating of the catholyte with farnesene – Compound 1 is greater. Nevertheless, the use of Compound 1 alone is possible and improves the performance compared to coating with the squalene-farnesene mixture.Thus, the contribution of the coating by the new molecules of the present invention makes it possible to improve the electrochemical performances of the battery while reducing the phenomenon of aging and parasitic reaction, reflecting a good coating of the sulfide catholytes and a better interaction with the different components within the positive electrode regardless of the sulfide electrolyte used as catholyte. Figure 20 shows a plot of discharge and charge capacity (mAh / g) and coulombic efficiency (%) versus cycle number for Cell 1 (open symbols) containing Li6PS5Cl sulfide solid electrolyte of a farnesene – squalene mixture as catholyte, and for Cell 8 (full symbols) containing Li6PS5Cl sulfide solid electrolyte coated with a squalene – Compound 15 mixture as catholyte as described in Example 4(a).Thus, coating the catholyte with a mixture of squalene - Compound 15 makes it possible to obtain electrochemical performances similar to those obtained for the farnesene - squalene mixture. Thus, it has been demonstrated that the use of a new coating compound makes it possible to maintain the performances of this type of battery. Example 5 – Compatibility with solvents With the Li catholyte. 5.4 PS 4.1 O 0.3 ClBr 0.5 I 0.1, it is necessary to use the solvents orthoxylene - diethyl carbonate - tetrahydrofuran to prepare the positive electrode as described in Example 3(a) because a degradation of electrochemical performance is observable when using the solvent toluene-tetrahydrofuran (e.g., at 60-40). To verify the effect of coating on the stability of these lithium-deficient, halogen-doped oxysulfide-type sulfides, 120 mg of sulfide was dispersed in a mixture of toluene-tetrahydrofuran solvents (80-20). After 30 min, the sulfide powder was decanted, and photographs shown in Figure 21 were taken for the catholyte Li5.4PS4.1O0.3ClBr0.5I0.1 coated in (a) with a mixture of farnesene – squalene (P-B), in (b) with Compound 2 (P-8) and in (c) with Compound 1 (P-7). A bright yellow coloration is visible in (a), confirming an advanced degradation of the catholyte Li5.4PS4.1O0.3ClBr0.5I0.1 even though it is coated with squalene-farnesene.However, in the context of the coating based on Compound 2 (in (b)) or Compound 1 (in (c)), sulfide is still in suspension after 30 min and the coloring of the solvent is much less yellow, demonstrating the protective effect of the new coating molecules with respect to the reaction of the sulfide with different solvents. It is thus possible to envisage the use of NMP or other solvents, previously contraindicated due to their reaction with sulfides, thanks to the addition of these new organic coating molecules and / or combination. Several modifications could be made to one or other of the embodiments described above without departing from the scope of the present invention as envisaged. The references, patents or scientific literature documents referred to in the present application are incorporated herein by reference in their entirety and for all purposes.
