ORGANIC-INORGANIC COMPOSITE ANION EXCHANGE MEMBRANE CONTAINING POLYVINYLIDENE FLUORIDE POLYMER FOR NON-AQUEOUS REDOX FLOW BATTERY AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to an anion exchange membrane comprising a polyvinylidene fluoride polymer for a non-aqueous redox flow battery. According to various embodiments of the present invention, an organic-inorganic complex polymer of the present invention is capable of increasing physical strength and thermal stability in comparison with the conventional organic polymer having low physical strength and thermal stability, having excellent dimensional stability and mechanical strength with less change in contraction and swelling than the conventional Neosepta AHA anion exchange membrane, and representing effects of high coulombic efficiencies and high voltage efficiencies with excellent thermal stability and chemical resistance.
