Ion-exchange membrane is also named as proton conductive membrane, is a key component in VRFB(vanadium redox flow battery) system. As the based material for proton-exchange membrane, vinylidene fluoride privides good chemical properties including oxidation resistance and good acid resistance. PVDF materials introduce polymeric hydrophilic/hydrophobic interactions into membrane formation, and propose a general and straightforward strategy for preparing membranes with nanometer-scale pores.

We can manufacture membranes for VRFB in batch with good chemical and mechanical resistance, high conductivity, low permeability of vanadium ions and low cost. Ion-exchange Membrane is able to be applied in high corrosive medium including acid or xidant, completely meets the performance demandings of vanadium redox flow battery, and also can be used in industries of gold recovery and acid recovery.
