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.
Électrolyte polymère pour un générateur électrochimique à base d'au moins un polymère à quatre branches, d'au moins un poly(vinylyldiènefluoride), un copolymère poly(vinylydiène fluoro-co-hexafluoropropène), un poly(tetrafluoroethylène), un poly(éthylène-co-propylène-co-5-methylène-2- norbornène) ou un copolymère éthylène propylène-diène, un polyol, un poly(méthylmétacrylate, un poly(acrylonitrile), SiO2-Al2O3, ou nano TiO2 enrobé ou non d'une matière organique. Cet électrolyte permet la préparation de compositions électrolytiques utilisables dans des dispositifs électrochimiques à haute performance.
