Rechargeable aqueous batteries with Zn 2 + as a media-ion are promising candidates for large-scale energy storage because of their intrinsic safety, low-cost and high energy-intensity. Vanadium based cathodic materials have gained significant attention in aqueous zinc-ion batteries (AZIBs) due to their high capacity and satisfactory cycle stability. However, more facile and efficient fabrication methods should be explored when considering future realistic application. Herein, commercial V 2 O 5 cathodes with oxygen vacancies were fabricated through a simple mechanical ball milling method. The results suggest that mechanical force can directly induce the oxygen vacancies in commercial V 2 O 5 , which significantly enhance the diffusion of Zn ions. The oxygen vacancyÀ V 2 O 5 (O v À V 2 O 5 ) shows much higher capacity than the pristine commercial V 2 O 5 and the cyclic stability reached 2500 times. O v À V 2 O 5 cathode with a facile synthesis technology is a promising candidate for future highperformance, low-cost, safe, and environment-friendly Zn battery devices.
