Patent

CA 2163336

An ionic conducting material, the preparation thereof and uses of said material are disclosed. The material includes at least one solution of at least one ionic compound in an aprotic solvent, which compound is selected from compounds (1/mM)?+¿[(ZY)¿2?N]?-¿, (1/mM)?+¿[(ZY)¿3?C]?-¿, (1/mM)?+¿[(ZY)¿2?CQ]?-¿, Wherein Y is SO¿2? or POZ; Q is -H, -COZ or Z; each substituent Z is independently a fluorine atom or an optionally perfluorinated organic group optionally having at least one polymerisable function, one of substitutents Z being a fluorine atom; and M is a cation. The material is useful in electrochemical generators, supercapacitors, polymer doping and electrochromic devices.

L'invention concerne un matériau à conduction ionique, sa préparation et ses utilisations. Le matériau comprend au moins un composé ionique en solution dans un solvant aprotique, choisi parmi les composés (1/mM)+[(ZY)2N]-, (1/mM)+[(ZY)3C]-, (1/mM)+[(ZY)2CQ]-, dans lesquels Y représente SO2 ou POZ; Q représente -H, -COZ ou Z; chaque substituant Z représente de manière indépendante un atome de fluor ou un groupe organique perfluoré ou non qui possède éventuellement au moins une fonction polymérisable, l'un au moins des substituants Z représente un atome de fluor; M représente un cation. Application aux générateurs électrochimiques, aux supercapacités, au dopage des polymères, aux dispositifs électrochromes.
