Abstract：

A novel polybenzimidazole (PBI)-based blended membrane was fabricated by physically blending cellulose acetate (CA) and polyvinylpyrrolidone (PVP) with the rigid-structured PBI matrix. PVP acted as a pore-forming agent, increasing membrane porosity, while the incorporation of CA reduced swelling and enhanced mechanical strength. A comprehensive evaluation of membranes properties,including mechanical properties, water uptake, swelling ratio, area resistance and ionic conductivity, revealed that the PBI blended membrane with 2.5% CP exhibited the most favorable electrochemical performance and the overall performance had certain advantages. When applied in an alkaline aqueous organic redox flow battery (AORFB) using 2,6-dihydroxyanthraquinone (2,6-DHAQ) and potassium ferrocyanide {K4[Fe(CN)6]} as active species, the AORFB assembled with the 2.5%CPPBI membrane achieved a maximum power density of 159 mW/cm2 and an energy efficiency of 82.8% at a current density of 80 mA/cm2, outperforming the commercial Nafion117 membrane. Moreover, the system demonstrated excellent cycling stability, with a capacity decay rate of only 0.000 6% over 500 charge-discharge cycles.
