Abstract: The present invention relates to asymmetric sulfonamide compounds comprising at least: one polycyclic group, Ar, formed of two to six rings, at least one of which is aromatic, a linear or branched, saturated or unsaturated aliphatic chain, said chain possibly being interrupted by one or more heteroatoms, said group Ar and said aliphatic chain being covalently bonded via a spacer represented by a sulfonamide unit —SO2—NH— or its anionic form —SO2—N−-; and, optionally a counter-cation of the anionic form of the sulfonamide unit, chosen among the alkali metals and the proton H+. These compounds are of particular interest as single-ion conducting polymer electrolyte.

Abstract: The present invention relates to a comb polymer comprising a main chain formed from 1-ethenyl- and/or 1-allyl-2,3,4,5,6-pentafluorobenzene monomers and polymeric side chains grafted in the para position of the pentafluorophenyl groups, in which said polymeric side chains are linked to said main chain by an oxygen atom, the molar grafting rate of polymeric side chains being greater than or equal to 50%.
It also relates to a method for the preparation of such a comb polymer.

Abstract: Thermotropic ionic liquid crystal molecules, comprising a so-called rigid part, a so-called flexible part bonded covalently, directly or via a spacer, to said rigid part, and one or more ionic groups bonded covalently to said rigid part. Said molecules can be used as electrolytes in an electrochemical device, in particular a lithium-ion battery.

Abstract: The present invention relates to a solid polymer electrolyte comprising: at least one comb polymer comprising a main chain formed from 1-ethenyl- and/or 1-allyl-2,3,4,5,6-pentafluorobenzene monomers, some of the monomer units of the main chain bearing polymeric side chains based on polymers that are solvents for alkali metal or alkaline-earth metal salts; said chains being grafted in the para position of the pentafluorophenyl groups; and at least one alkali metal or alkaline-earth metal salt, in particular a lithium salt. The invention also relates to a process for preparing a solid polymer electrolyte film and to the use thereof in an electrochemical system, in particular a lithium battery.
