Schematic of aqueous ZIBs based on Zn0.25V2O5 cathode. Due to the water molecules between the V2O5 layers, the interlayer space expands. b The related HRTEM image of the Zn0.25V2O5·nH2O nanobelts. c Schematics showing the co-intercalation of water molecules accompanying Zn2+ in/out of the interlayer space of V2O5 layers during charging and discharging process [67].
