Thin-film composite membranes for electrochemical systems

Abstract

Membranes and related applications, including electrochemical systems, are generally described. In some aspects, the membranes are thin-film composite membranes (e.g., formed by interfacial polymerization or otherwise). The membrane, which may include a polymeric selective layer adjacent to a porous support layer, may be configured to be suitable for nonaqueous electrochemical systems (e.g., nonaqueous redox flow batteries) in which relatively low area-specific resistance and relatively lower permeance of redox-active species are desired. In some aspects, the membrane (e.g., as part of its selective layer) includes a cross-linked polymeric network with a relatively high porosity and/or surface area, which may be in part attributed to the use of monomers having three-dimensional structures.
