BILAYER ELECTROLYTE MEMBRANE AND A REDOX FLOW BATTERY COMPRISING A BILAYER ELECTROLYTE MEMBRANE

NºPublicación: WO2019137696A1 18/07/2019

Solicitante:

SCHERRER INST PAUL [CH]

EP_3511999_A1

Resumen de: WO2019137696A1

The present invention has the objectives to provide an electrolyte membrane and a method for generating such an electrolyte membrane wherein the resistance of the electrolyte membrane should be as low as possible to minimize ohmic losses. Concurrently, the electrolyte membrane should have a low permeability for the redox- active species. If redox-active species are still crossing the electrolyte membrane, this transport should be balanced during charge and discharge in order to prevent a net vanadium flux and the associated capacity fading. Moreover, the electrolyte membrane should be mechanically robust, chemically stable in the respective electrolyte solution, and be of low cost. The present invention describes a family of ion exchange membranes comprising a bilayer architecture to achieve these requirements. The bilayer membrane comprises two polymers, i) a polymer comprising N-heterocycles with electron lone pairs acting as proton acceptor sites and ii) a mechanically robust polymer that acts as a support, which can be a dense cation exchange membrane or a porous support layer as shown in Figure 2. This bilayer architecture allows the use of a very thin (<15 μm) polymer film on a supporting polymer to minimize the ohmic (ionic) resistance and tune the electrolyte transport properties of the membrane.
