Improving Ionic Conductivity of Electrolytes Based on Lithium Imidazolate Salts

摘要

The present invention relates to an electrolyte composition, the electrolyte composition comprising: At least one lithium salt of formula (A): (A) Wherein Rf is a fluorine atom, a nitrile group, an optionally fluorinated or perfluorinated alkyl group having 1 to 5 carbon atoms, an optionally fluorinated or perfluorinated alkoxy group having 1 to 5 carbon atoms, or optionally 1 to 5 carbon atoms Fluorinated or perfluorinated oxa-alkoxy groups; And The following solvent mixtures: ethylene carbonate, γ-butyrolactone, and methyl propanoate. The invention also relates to the use of the compositions in lithium ion batteries.
