New membranes for redox flow batteries have been designed to have high proton conduction and low vanadium ion diffusion. These poly(sulfone)-based membranes have small ionic channels which prevents diffusion of large molecules or hydrated ions while maintaining a high sulfonic acid density on the backbone which promotes proton conductivity. The structure-property relationships for these types of membranes will be discussed and the methods by which the design of new materials with specific transport properties for a desired application will be elucidated. Specifically, low-cost, high performance membranes for vanadium redox flow batteries will be reported.
