Dual-ion doped vanadium oxide nanobelts as the cathode in rechargeable aqueous zinc ion battery

Rechargeable aqueous zinc ion batteries (RAZBs) have been used extensively because of their safety and low-cost. As an available cathode material for ZIBs, layered vanadium oxide (V2O5) has been considered due to its high specific discharge capacity. Because V2O5 is slightly soluble in water, it is suitable for doping V2O5 with metal ions to stabilize its layered structure and decrease the solubility of V2O5 in aqueous electrolyte systems. Hydrothermal method will be used to insert metal ions into V2O5 interlayer and shape the commercial V2O5 into nanobelts. In this research, we will experiment with the molar ratio of metal ions to active material to determine the ratio and the synthesis conditions that provides the best cycling performance and that enhances the specific discharge capacity of V2O5 cathode for RAZBs.
