The invention concerns an electrolyte composition, comprising: - a lithium bis(fluorosulfonyl)imide salt and/or a lithium 4,5-dicyano-(trifluoromethyl) imidazolate salt; and - a solvent of formula (I): in which: - n is an integer of between 0 and 15, - R1, R2 and R3 represent, independently, a halogen atom or a C1 to C6 linear or branched alkyl group, - X represents either a covalent bond or a C1 to C6 linear or branched alkylene alkenylene or alkynylene group, - Y represents either an -(OCh2Ch2)m- group, or an -(N(CH3)CH2CH2)m- group, m being an integer of between 0 and 15, provided that m is different from 0 when X represents a covalent bond, and - R4 represents a cyano, cyanate, isocyanate, thiocyanate or isothiocyanate group. |
