Aqueous zinc-ion batteries (ZIBs) enjoy a good reputation for being safe, affordable to produce, and ecologically friendly due to the use of water-based electrolytes. The main factors restricting the development of ZIBs, however, are the negative effects of dendrite deposition on the zinc anode and the dissolution of common cathodes such as Mn and V-based cathodes. Various techniques have been used to address these issues, including regulating the electrolyte concentration or solvation structure, developing a coating or current collector to lessen anode dendrite growth, and improving the structural stability of the cathode. Recently, functionalized separator strategies have gained popularity as effective ways to improve ZIB performance. The use of a functionalized separator is also a practical technique to save costs and increase the volumetric energy density of the battery by substituting a functionalized separator for the usual thick and expensive glass fiber separator.

The massive surge in the consumption of fossil fuels and the resulting environmental degradation necessitates the progression of renewable energy sources and energy storage/conversion technologies. The utilization of polymers characterized as being highly energy efficient and cost-effective is among the highly intriguing areas of research.
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
