Abstract: Membranes for flow battery cells are provided herein. In one example, a membrane for a flow battery system includes a microporous substrate having a first surface and a second surface, opposite the first surface, and a coating of ion-conducting polymer on the first surface and the second surface, wherein one or more pores of the microporous substrate are at least partially filled with the ion-conducting polymer.
