Abstract

Polymer electrolyte for an electrochemical generator based on at least a four branched polymer, at least a poly(vinylyldienefluoride), a poly(vinyldiene fluoro-co-hexafluoropropene copolymer), a poly(tetrafluoroethylene), a poly(ethylene-co-propylene-co-5-methylene-2-norbornene) or an ethylene propylene-diene copolymer, a polyol, a poly(methylmethacrylate, a poly(acrylonitrile), SiO2Al2O3, or nano TiO2 non coated or coated with an organic material. This electrolyte allows to prepare electrolytic compositions that can be used in high performance electrochemical devices.
