PREPARATION OF PROTON CONDUCTIVE MEMBRANE FOR FLOW BATTERY

摘要：

Vanadium redox flow battery(VRB) is regarded as a promising technique for mass electricity storage to meet the need in photovoltaic and wind power system. The proton conductive membrane is one of the key materials in VRB, playing the role of separating the positive and negative electrolytes and conducting hydrogen ions. This study proposes a general approach to the preparation of nanoporous membranes through polymeric hydrophilic/hydrophobic interactions and removal of polyion aggregates by water immersion. Poly(vinylidene fluoride) (PVDF) and sodium allyl sulfonate (SAS) serve as the membrane material and pore-generator, respectively, resulting in chemically stable and oxidation-resistant membranes with various potential applications.
