💡 Novelty & Significance:
This work pioneers universal ligand-field engineering via organic cation preintercalation to boost vanadium oxide cathode voltage in aqueous zinc batteries. BMIM+ optimally tunes [VO6] coordination, lowering the V 3d-band center to widen V-O energy separation and raise operating voltage, while achieving 505 mAh g–1 and 94% retention over 15,000 cycles. The strategy generalizes to V6O13 and KV3O8, offering broad design principles.
