An electrolytic composition including at least one lithium salt of formula (A) wherein Rf represents a fluorine atom, a nitrile group, an optionally fluorinated or perfluorinated alkyl group having from 1 to 5 carbons, an optionally fluorinated or perfluorinated alkoxy group having from 1 to 5 carbons or an optionally fluorinated or perfluorinated oxa-alkoxy group having from 1 to 5 carbons; and the following solvent mixture: ethylene carbonate, &#x3b3;-butyrolactone, and methyl propanoate. Also, to the use of the compositions in Li-ion batteries.

Improving the ionic conductivity of an electrolyte based on lithium imidazolate salts

The invention relates to a composition comprising an ionic liquid consisting in the combination of a pyrrolidinium cation and a nitrate anion and comprising a solvent selected from lactone solvents, carbonate solvents, nitrile solvents and mixtures thereof. The composition may be used as an electrolyte, for example, for such applications as energy storage devices.

Composition comprising a specific ionic liquid

The present invention relates to ionic liquids comprising, as cation, a specific phosphonium cation, as anion, a formate anion, which can be used, alone or as a mixture, to constitute electrolytes for energy storage devices.
