Abstract

We present a high-performance LIB anode featuring a MOF-derived CeO2/a-FeαOβ heterostructure. Electronic coupling via 4f–3d orbital hybridization enables a synergistic mechanism that stabilizes oxygen redox, minimizes lattice strain, and accelerates ion transport, achieving high reversible capacity and exceptional long-term stability.
