Patent

CA 2192895

The invention relates to ionically conductive materials including at least one compound corresponding to the following formula (I): Image (I) in which the groups X and X' are identical or different and denote at least one electrophilic group in an ortho, meta and/or para position and M denotes an alkali or alkaline-earth metal, in solution in a solvent including a macromolecular material or a polar aprotic solvent or solvent mixture. The electrophilic groups X, X' may be chosen from nitro, C1-C5 perfluoroalkyl, CN, halogen, vinyl, CO2R and SO2R groups where R denotes a C1-C5 linear or branched alkyl radical and the metal M may be chosen from lithium, sodium, potassium, caesium, magnesium, calcium and barium. The invention also relates to a process for the preparation of the abovementioned compounds. The invention applies more particularly to the manufacture of electrochemical generators including an electrolyte based, at least partially, on these ionically conductive materials.
