Definitions
- the present invention relates to novel electrolytic compositions comprising at least one coordination complex comprising lithium and at least one ligand of the trifluoromethylphenate type, these novel compositions being applicable in the field of electrolytes, more particularly electrolytes of lithium-ion batteries.
- One of the general areas can therefore be defined as that of lithium-ion batteries.
- the lithium-ion 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, via a conductive electrolyte of lithium ions.
- lithium cations coming from a negative electrode which are interposed in the acceptor network of the positive electrode, while electrons resulting from the reaction at the electrode negative 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 inventors of the present invention have set out to develop new electrolyte compositions conductive lithium ions, not requiring the use of lithium salts dissolved in an organic solvent, and which are simple manufacturing.
- At least one coordination complex comprising lithium and one or more ligands thereof, this or these ligands corresponding to a phenate compound comprising at least one trifluoromethyl group;
- ligand means a compound capable of sharing a negative charge or an electronic doublet with lithium so as to form a coordination link.
- the above-mentioned phenyl compound serving as a ligand may be a phenate compound having the following formula (I):
- R 1 to R 5 represents a trifluoromethyl group, while the other groups, when they do not all represent a trifluoromethyl group, represent a hydrogen atom.

- the lithium complexes can be manufactured by reaction of a phenol compound comprising at least one trifluoromethyl group with an organolithium compound, in particular an alkyl lithium compound, such as n-butyllithium, this reaction being conventionally carried out in a medium comprising an ether compound. .
- reaction scheme By way of example, this reaction can be illustrated by the following reaction scheme:
- This reaction is conventionally carried out in an anhydrous medium and under an inert atmosphere for a relatively short reaction time, for example a reaction time of less than 3 hours.
- the reactivity of the alkyl lithium compounds with respect to the phenol derivative compounds as shown above allows a total conversion of the starting reagents.
- the starting reagents compounds derived from phenol and alkyllithium compound
- the purification treatment of the product obtained which can be summarized as a simple evaporation of substances volatile, such as butane (generated when n-butyllithium is used).
