Popis: | An advanced ion-selective membrane containing a dynamic hydroxyl-based 3D H-bond network is first proposed for improved efficiencies and stability in flow battery applications. The 3D H-bond network structure is constructed by the nanoscale aggregation of hydrophilic dense-hydroxyl side chains anchored to hydrophobic polybenzimidazole. This unique dynamic H-bond network creates proton transport highways as well as vanadium permeation barriers across the membrane, leading to an ultralow vanadium ion permeability ( |
