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. 

Pentacyclic anion salt and use thereof as an electrolyte

A process for preparing membranes formed by (per) fluorinated ionomeric electrolytes salified with the lithium ion, comprising the following steps:

Process for preparing ionomeric membranes

The present invention concerns the preparation of composite biomaterials constituted by hyaluronic acid and the derivatives thereof in combination with polymers that have electrically conductive properties. In particular, the methods of preparing biomedical devices formed by a two- or three-dimensional polysaccharide matrix and by an electrically conductive membrane. The matrix is constituted by hyaluronic acid derivatives in the form of membranes, woven fabrics, nonwoven felts, meshes, gauzes, guide channels or sponges, while the electrically conductive membrane is constituted by a film of polypyrrole (polymer conductor) in combination with hyaluronic acid or a derivative thereof (doping agent).
