In recent years, vanadium redox flow batteries (VRFB) have captured immense attraction in electrochemical energy storage systems due to their long cycle life, flexibility, high-energy efficiency, time, and reliability. VRFB, polymer membranes play a significant role transporting protons for current transmission act as barriers between positive negative electrodes/electrolytes. Commercial (such Nafion) are the widely used IEM VRFBs outstanding chemical stability proton conductivity. However, membrane cost increased ions permeability limit its commercial application. Therefore, various modified perfluorinated non-perfluorinated been developed. This comprehensive review primarily focuses on developments of hybrid composite with inorganic TiO2 nanofillers VRFB applications. Hence, fabrications performed alter physicochemical properties attaining perfect IEM. Additionally, embedding -SO3H groups by sulfonation nanofiller surface enhances conductivity mechanical strength. Incorporating (sTiO2, organic silica TiO2) into Nafion other (sPEEK sPI) has effectively influenced better performances. provides an overall spotlight impact TiO2-based matrix
