New, stable, low-cost poly(aromatic) proton exchange membranes have shown improved performance in flow battery devices.  The high performance of these materials in flow cell testing is a consequence of the low vanadium permeability of the ionc-conducting membrane used to separate the anolye and catholyte in the cell.  The low vanadium permeability is facilitated by creating materials with small-scale ionic domains, which allow protons to move through the material, but vanadium hinder ion permeation.  This presentation will describe the critical issues for deploying new membranes in flow batteries and demonstrate how optimized molecular design of these polymer membranes leads to improved properties that can be directly correlated to better system performance.
