To improve the electrochemical activities of graphite felt (GF) electrodes of all vanadium flow battery (VRB)
nano-Ga2O3 were deposited on the surface of graphite felt (GF) electrode in an VRB using thermal decomposition. Electrochemical performance and morphology of GF were studied by cyclic voltammetry (CV)
polarization curves
scanning electron microscopy (SEM)
X-ray photoelectron spectroscopy (XPS) and charge-discharge test. The results showed that Ga2O3 has catalytic effects towards redox reaction of the electrode
when modifying the GF with Ga2O3
the anodic and cathodic reactivity of the VRB were increased by 13% and 18% compared with pristine one
