Abstract
The invention relates to a polymeric electrolyte for an electrochemical generator, comprising at least one four-branched polymer, at least one poly(vinylidene fluoride), a co-polymer of poly(vinylidene fluoride-co-hexafluoropropene), a polytetrafluoroethylene, a poly(ethylene-co-propylene-co-5-methylene-2-norbornene) or a copolymer of ethylene propylene diene, a polyol, a polymethylmethacrylate, a polyacrylonitrile, SiO¿2?-Al¿2?O¿3?, or nano TiO¿2? coated or not with an organic material. Said electrolyte permits the preparation of electrolytic compositions which find application in high-performance electrochemical devices.
