Abstract
We propose and demonstrate a novel flow battery architecture that replaces traditional ion-exchange membranes with less expensive heterogeneous flow-through porous media. Compared to previous membraneless systems, our prototype exhibits significantly improved power density (0.925 W cm[superscript -2]), maximum current density (3 A cm[suprescript -2]), and reactant crossover, shown by the proposed experimentally-validated crossover model.
