In this work, novel sodium-intercalated vanadium oxide nanowire electrode materials (NaXV@CC) were successfully designed as cathode for Aqueous Zinc-Ion Batteries (AZIBs) through a two-step electrochemical process. The optimized material, Na30V@CC, exhibited superior capacity, excellent rate capability, and outstanding stability. intercalation of sodium ions into the lattice induced significant transformation in overall nanostructure, leading to altered morphology. This unique structural design provided abundant active sites efficient ion transport pathways, thereby enhancing performance. charging discharging capacities 343.3 330.4 mAh·g−1 at 0.2 A·g−1, respectively, capacity was maintained 90 8 A·g−1. battery demonstrated exceptional retention over 3000 cycles 5 highlighting its long-term Moreover, reaction governed by combination diffusion surface processes. Na30V@CC system reduced impedance improved zinc rates. study offers valuable insights performance vanadium-based cathodes AZIBs.
