A pentacyclic anion salt is provided for use thereof in electrolyte compositions. The compound has an inorganic, organic or organometallic cation M of valency m (1&#x2266;m&#x2266;3) and m anions corresponding to the formula (I) in which Ris a &#x2014;CFZ'Z&#x2033; group in which Z&#x2032; is F or a perflouroalkyl group having from 1 to 3 carbon atoms, and Z&#x2033; is an H, F or Cl group, an optionally fluorinated or perfluorinated alkoxy group having from 1 to 5 carbon atoms, an optionally fluorinated or perfluorinated oxaalkoxy group having 1 to 5 carbon atoms or an optionally fluorinated or perfluorinated alkyl group having from 1 to 5 carbon atoms; Z&#x2033; being other than F when Z&#x2032; is F. An electrolyte composition comprises said salt in solution in a liquid solvent or a polymer solvent.

Five-membered cyclic anion use thereof as an electrolyte

The invention relates to a pentacyclic anion salt and to the use thereof in electrolyte compositions. The compound comprises an inorganic, organic or organometallic cation M of valency m (1&#x2266;m&#x2266;3) and m anions corresponding to the formula (I) in which Ris a &#x2014;CFZ'Z&#x2033; group in which Z&#x2032; is F or a perfluoroalkyl group having from 1 to 3 carbon atoms, and Z&#x2033; is an H, F or Cl group, an optionally fluorinated or perfluorinated alkoxy group having from 1 to 5 carbon atoms, an optionally fluorinated or perfluorinated oxaalkoxy group having from 1 to 5 carbon atoms or an optionally fluorinated or perfluorinated alkyl group having from 1 to 5 carbon atoms; Z&#x2033; being other than F when Z&#x2032; is F. An electrolyte composition comprises said salt in solution in a liquid solvent or a polymer solvent.
