Progress in Vanadium-Based Oxides Cathode Materials for Aqueous Zinc-Ion Batteries

Aqueous zinc-ion batteries (AZIBs) have been paid increasing attention by researchers because of its advantages of low cost, high safety and environmental friendliness. In recent years, vanadium-based oxides have been considered as potential cathode materials for AZIBs due to their wide variety of oxides, high theoretical capacity and excellent rate performance. In this paper, the structural characteristics and newly advance of vanadium-based oxides mainly encompassing V2O5 and VO2 as cathode materials for AZIBs are reviewed. The key problems faced by vanadium-based oxides in AZIBs and the corresponding solutions are highlighted. Also, the future research trends of vanadium-based oxides as zinc storage materials was prospected.
