Definitions
- the present invention relates to specific fluorinated compounds, to their process of preparation and to their use as solvents capable, in particular, to allow the dissolution of lithium salts.
- Lithium batteries are particularly interesting for areas where autonomy is an essential criterion, as is the case in the fields of computers, video, mobile telephony, transport such as electric vehicles, hybrid vehicles, or medical, space, microelectronics.
- the lithium batteries are based on the principle of intercalation-deintercalation of lithium within the constituent materials of the electrodes of the electrochemical cells of the battery.
- the reaction at the origin of the current generation involves the transfer, by means of a conductive electrolyte of lithium ions, of lithium cations coming from a negative electrode which are interposed in the acceptor network of the positive electrode, while electrons resulting from the reaction to the negative electrode will feed the external circuit, to which are connected the positive and negative electrode.
- These electrolytes may consist of a mixture comprising at least one organic solvent and at least one lithium salt for conduction of said lithium ions, which requires that the lithium salt be dissolved in said organic solvent.
- the organic solvents used to perform this function are conventionally carbonate solvents, such as ethylene carbonate, dimethyl carbonate or diethyl carbonate.
- -X 1 represents a sulfur atom
- X 2 and X 3 represent an oxygen atom or a sulfur atom with the proviso that, if one of said X 2 and X 3 is a sulfur atom, the other of said X 2 and X 3 is an atom oxygen and vice versa;
- R 1 -R 1 , R 2 and R 3 represent, independently of one another, a fluorine atom or a hydrogen atom, provided that at least one of said R 1 , R 2 and R 3 represents a fluorine atom.
- R 1 , R 2 and R 3 each represent a fluorine atom, in which case the compounds in accordance with the invention correspond to the following formula (IV):
- the fluorinated compounds of the invention may be prepared by carrying out a process comprising a reaction step of an epoxy compound of formula (VII) below:
- a specific epoxide compound is hexafluoropropene oxide of the following formula (IX):
- the present reaction is advantageously carried out in the presence of a reaction catalyst having the ability to accelerate the chemical reaction between the epoxide compound of formula (VII) and the compound of formula (VIII). More specifically, the catalyst will interact with the oxygen atom of the epoxide compound to improve its reactivity. After reaction of the epoxide compound of formula (VII) with the compound of formula (VIII), the catalyst is regenerated in its initial form.
- halogenated salts such as sodium chloride, sodium bromide, sodium iodide, potassium chloride, potassium bromide, potassium iodide, lithium chloride, lithium bromide;
- organic salts such as sodium phenate, sodium acetate, sodium ethoxide, sodium tert-butoxide, potassium tert-butoxide, tetrabutylammonium iodide, tetrabutylammonium bromide;
- phosphonium salts such as phosphonium iodide
- cyclic organic compounds such as phenol, imidazole and pyrazole
- the process of the invention can be implemented in a closed system, such as an autoclave.
- the reaction step may be carried out in a temperature range of from 50 ° C to 225 ° C for a pressure range of from 1 to 40 bar.
- the process may comprise a step of isolating the compound (s) from the reaction medium, this isolation stage being able to consist of a succession of operations of extraction, desiccation and evaporation of the organic solvent.
- the compounds according to the invention have particular properties, such as a sub-ambient melting temperature (for example, less than 0 ° C.), an ability to dissociate the ionic entities (in particular due to a dielectric constant, which can be greater than 20) and a chemical inertness vis-à-vis the lithium salts.
- this organic solvent can enter into the constitution of an electrolyte comprising at least one lithium salt for a lithium battery.
- the invention also relates to: the use of a fluorinated compound as defined above as an organic solvent of at least one lithium salt;
- composition more specifically a liquid composition, which may be a conductive electrolyte of lithium ions, comprising at least one fluorinated compound as defined above and at least one lithium salt; and
- a lithium battery comprising at least one electrochemical cell comprising an electrolyte as defined above disposed between a positive electrode and a negative electrode.
- the lithium salt may be chosen from the group consisting of L 1 PF 6 , L 1 Cl O 4 , LiBF 4 , Li AsF 6 , L 1 CF 3 S O 3, LiN (CF 3 S O 2) 3, LiN (C 2 F 5 S0 2 ), the lithium bistrifluoromethylsulfonylimide (known by the abbreviation LiTFSI) LiN [S0 2 CF 3 ] 2 and mixtures thereof.
- LiTFSI lithium bistrifluoromethylsulfonylimide
- the aforementioned liquid electrolyte can be led into the electrochemical cells of the lithium batteries to impregnate a separator, which is disposed between the positive electrode and the negative electrode of the electrochemical cell.
- This separator may be a porous material, such as a polymeric material, capable of accommodating in its porosity 1 'liquid electrolyte.
- the electrolyte is composed of at least one lithium salt and at least one organic solvent, which may consist solely of one or more compounds of formula (I) according to the invention or may further comprise at least one other aprotic solvent, such as dimethyl carbonate, diethyl carbonate, ethyl and methyl carbonate, ethylene carbonate and propylene carbonate.
- organic solvent such as dimethyl carbonate, diethyl carbonate, ethyl and methyl carbonate, ethylene carbonate and propylene carbonate.
- positive electrode is meant, conventionally, in what precedes and what follows, the electrode which acts as a cathode, when the generator delivers current (that is to say when it is in the process of discharge) and which acts as anode when the generator is in charging process.
- negative electrode is meant, conventionally, in what precedes and what follows, the electrode which acts as anode, when the generator delivers current (that is to say when is in the process of discharge) and which acts cathode, when the generator is in process of charge.
- the negative electrode may be based on an active material that may be a carbonaceous material, such as graphite, or a type of oxide type material Li 4 Ti 5 O 12, said material being able to be associated with a polymeric binder such as polyvinylidene fluoride, the resulting mixture can be deposited on a current collector, for example, aluminum.

- the hexafluoropropene oxide being gaseous is carried out in a 100 ml Hastelloy Parr autoclave equipped with a manometer, a bursting disk and gas introduction and release valves.
- An electronic device makes it possible to control both the stirring and the heating of the autoclave.
- the pressure measured in the autoclave reaches 12 bars and then decreases and remains at 8 bars at 50 ° C.
- the autoclave is cooled 14 hours after the start of the immersion reaction for 30 minutes. minutes in an ice bath. The reactor is then degassed and the reaction residue is collected.
- the compound was recovered at a yield of 76%.
- the 19 F NMR spectrum of the compound has the following signals:
