Harnessing 4f–3d synergy in Ce–Fe heterostructure: a PBA-derived oxygen reservoir for stable high-capacity lithium storage
We present a high-performance LIB anode featuring a MOF-derived CeO<sub>2</sub>/a-Fe<sub><i>α</i></sub>O<sub><i>β</i></sub> heterostructure. Electronic coupling <i>via</i> 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.
