Abstract
The invention relates to an ionically conductive material, to its preparation and to its uses. The material includes at least one ionic compound in solution in an aprotic solvent, chosen from the compounds (1/mM).sup.+ [(ZY).sub.2 N].sup.-, (1/mM).sup.+ [(ZY).sub.3 C].sup.- and (1/mM).sup.+ [(ZY).sub.2 CQ].sup.-, in which Y denotes SO.sub.2 or POZ, Q denotes --H, --COZ or Z, each substituent Z independently denotes a fluorine atom or an optionally perfluorinated organic group which optionally contains at least one polymerizable functional group, at least one of the substituents Z denoting a fluorine atom, and M denotes a cation. Application to electrochemical generators, supercapacities, to the doping of polymers and to electrochromic devices.
