💡 Novelty & Significance:
This work pioneers a one-step hydrothermal route coupling glucose-induced reductive reconstruction with Ni²⁺ incorporation, creating Ni-regulated hydrated vanadium oxide with coexisting H₂V₃O₈ and Ni-containing domains. DFT screening identifies Ni²⁺ for lowest Zn²⁺ migration barriers. The domain-balanced architecture enables 433.4 mAh g⁻¹ at 0.1 A g⁻¹ and 282.6 mAh g⁻¹ after 6000 cycles, establishing coupled reconstruction and guest-ion regulation for durable aqueous zinc-ion cathodes.
