💡 Novelty & Significance:
The novelty lies in engineering Ir─O─Ni interfacial bonds within Ir@Ni-MOF, which redistributes charge and downshifts the Ir d-band center, weakening LiO₂ adsorption. This enables a solution-mediated pathway forming nanosheet-like Li₂O₂, lowering overpotential to 0.76 V and sustaining over 400 cycles. It offers a precise electronic-structure strategy for high-performance Li-O₂ batteries.
