Vanadium oxide coated with conductive polymers for zinc-ion battery cathode
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 modifying V2O5 with conductive polymers to stabilize its crystalline structure and decrease the solubility of V2O5 in aqueous electrolyte systems. In-situ polymerization will be used to coat polymers on the V2O5 surface. In this research, we will experiment with the mass ratio of polymer to active material to determine the ratio that provides best cycling performance and that enhances the specific discharge capacity of V2O5 cathode for RAZBs.
