Abstract[English]
The present invention relates to the use of a membrane (M) in an aqueous redox flow battery (ARFB), wherein the membrane (M) comprises a non-crosslinked sulfonated polyarylene ether sulfone polymer (sP). The non-crosslinked sulfonated polyarylene ether sulfone polymer (sP) is prepared by a process comprising the step I) converting a reaction mixture (RG) comprising as components (A1) at least one non-sulfonated aromatic dihalogen sulfone, (A2) at least one sulfonated aromatic dihalogen sulfone, (B) at least one aromatic dihydroxy component, (C) at least one carbonate component, and (D) at least one aprotic polar solvent.[French]
La présente invention concerne l'utilisation d'une membrane (M) dans une batterie redox aqueuse (ARFB), la membrane (M) comprenant un polymère de polyarylène éther sulfone (sP) sulfoné non réticulé. Le polymère de polyarylène éther sulfone (sP) sulfoné non réticulé est préparé par un processus comprenant l'étape I) consistant à convertir un mélange réactionnel (RG) comprenant en tant que composants (A1) au moins un dihalogène sulfone aromatique non sulfoné, (A2) au moins un dihalogène sulfone aromatique sulfoné, (B) au moins un composant dihydroxy aromatique, (C) au moins un composant carbonate, et (D) au moins un solvant polaire aprotique.
