Summary: In recent years, vanadium redox flow batteries (VRFBs) have gained global attention due to their advantages of large scale, high safety, and long-term cyclability. However, the unsatisfactory kinetics of carbon-based anodes, especially graphite felt (GF), hinders the commercial application of VRFBs. To address this issue, a lamination layer of Nb-doped TiO2 (NTO) is introduced to a heat-treated graphite felt (HGF), which improves the surface properties of GF anodes and enables superior energy storage performance compared with other electrodes. The NTO-HGF anode demonstrates a higher energy efficiency of 82.03% compared to pristine GF.

Summary: This study investigates the effects of temperature on the performance of stack-scale vanadium redox flow batteries (VRFBs). It is found that temperature has a greater impact on the discharge capacity than on the energy efficiency.
