Abstract: This disclosure relates to free-standing, composite membranes that include an ion-selective polymer coating that covers at least one surface and partially penetrates into the pore structure of a polyolefin substrate. While the composite membranes do not have open, interconnected pores that connect each major surface, ion transport can take place through wetting of available pores and swelling of the ion-selective polymer coating accompanied by ion migration from one membrane surface to the opposite surface. Such composite membranes are useful for separating the anolyte and catholyte in a flow battery.

Abstract: The disclosed porous membranes and freestanding composites containing the porous membranes have a solution-cast three-dimensional polymer matrix defining interconnecting pores that provide overall first major surface-to-second major surface fluid permeability. The porous membranes and freestanding composites can be used to separate lead-acid battery electrodes. The porous membranes and freestanding composites can have high porosity and low electrical resistance while having both excellent flexibility and mechanical strength. This can reduce the probability of damage to the separators during battery assembly and also allow production of battery separators with a high overall height, but a minimal backweb thickness.
