Аннотация:A novel method of membrane preparation for use in vanadium redox flow batteries by preswelling of poly(2,5-benzimidazole) films in organic solvent followed by supercritical CO2 assisted solvent removal is proposed. Influence of the organic solvent type on the morphology, proton, and vanadyl ion transport properties is studied. The performance of the obtained membranes inside single cells of vanadium redox flow batteries is compared to pristine dense poly(2,5-benzimidazole) and Nafion 115 membranes.
