Ion-conducting membranes with excellent performance have attracted extensive attention from scientists. A recent work published in Chem by Guihua Yu et al. demonstrates the construction of fast and selective ion-transport channels in polymeric membranes based on pseudo-nanophase-separation strategy by supramolecular interactions, which exhibit high efficiency and good cycling stability for aqueous acidic redox flow batteries. The mechanism of fast proton transportation in PBI-x membranes is mainly regar...
