Abstract In this study, Li 4 Ti 5 O 12 (LTO) and TiO 2 nanocomposites uniformly were synthesized on the heat‐treated graphite felt through (HGF) hydrothermal heat treatment methods, denoted by LTO/TiO @HGF, which @HGF acts as effective electrocatalysts to enhance electrochemical activity in vanadium redox flow battery (VRFB) systems. The cyclic voltammetry (CV) curves of show higher peak current densities smaller separation than HGF, pristine (PGF) for catalyzing V 2+ /V 3+ VO₂ + /VO , indicating superior @HGF. VRFB using positive negative electrodes demonstrates an energy efficiency 82.89 % at 80 mA cm −2 . When is applied a high density 200 it still shows 62.22 %. However, PGF cannot perform any performance, HGF only performs 51.94 This improvement can be attributed uniform distribution nanowires surface presence oxygen vacancies increased number active sites ion absorption.
