An advanced organic-inorganic composite membrane is investigated to enhance mechanical and chemical stability of membrane for vanadium redox flow battery (VRFB). In order to improve chemical and mechanical stability of membrane, organic polymer is composed with inorganic material for VRFB. The inorganic material can be used as anti-oxidant for improving membrane chemical stability during long-term operation of VRFB. However, higher concentration of inorganic particles increased the hydrophobicity which may make membranes brittle. Therefore, the optimization of inorganic materials in polymer membrane is carried out for the application VRFB.
