Vanadium-based oxides with unique layered structures and multiple oxidation states have attracted considerable attention for aqueous zinc-ion batteries (AZIBs). However, the inferior conductivity nearly nonporous structural characteristics of commercial V2O5 inevitably hinder transport electrons/ions, inherently narrow interlayer spacing strong electrostatic interactions severely restrict further development cathodes. In this work, neodymium (Nd) ions were employed as guests to intercalate into MIL-88B(V)-derived (denoted OV-NVO) by a one-step hydrothermal process stable cathode materials AZIBs. Benefiting from its well-designed honeycomb-like porous structure, large surface area, expanded spacing, abundant oxygen vacancies, feeble interactions, OV-NVO delivered prominent discharge capacity 455.2 mAh g–1 at 0.1 A exhibited satisfactory rate capability (341.5 5.0 g–1) cycling stability (90.8% retention after 2000 cycles g–1). Impressively, assembled Zn//OV-NVO flexible battery can operate stably under extreme bending conditions exhibits superior electrochemical behavior. Furthermore, reversible Zn2+ storage mechanism evolution analyzed kinetic analysis, ex situ characterizations, density functional theory calculations. This synergistic strategy combining Nd-ion intercalation defect engineering provides an effective approach design high-performance vanadium-based materials, offering more possibilities practical applications
