Robust Ion‐Selective Membrane for Redox Flow Batteries Based on Ultralow Sulfonation Degree Poly(Ether Sulfone)

Low‐cost and high‐performance ion‐conducting membranes are of urgent need for the large‐scale launch of vanadium redox flow batteries. In this work, sulfonated poly(ether sulfone) (SPES) with extremely low sulfonation degree of 5% is utilized to prepare ion‐selective membranes, which possess signifi...
