Rechargeable aqueous zinc-ion batteries (ZIBs) are the prospective substitution for lithium-ion batteries applied in large scale energy storage system due to their low-cost, environmentally friendliness, and high safety. However, the development of cathodes in aqueous ZIBs suffers from sluggish Zn2+ migration. Herein, nitrogen doped V2O5 is introduced to resolve the above problem. N-doping lowers the bandgap energy of V2O5 to improve its electronic conductivity, and weakens the forces between Zn2+ and V2O5 to fasten Zn2+ diffusion. Further density functional theory (DFT) calculation testifies that N-doping reduces diffusion energy barrier and changes Zn2+ diffusion pathway from the vertical interlayer diffusion to planer intralayer diffusion. Meanwhile, the structural stability of electrode material also benefits from the N-doping, which can prevent the interlayer V2O5 from gliding or exfoliation during cycling. Profiting from these merits, N-doping V2O5 exhibits the outstanding electr
