💡 Novelty & Significance:
The novelty lies in a molten-perfusion-fluorination strategy confining pyrochlore-phase iron hydroxy fluoride within graphite layers via Fe–C bonds. This design creates a 3D open framework with abundant reactive sites and hydroxy anion substitution that softens conversion reactions. It enables sustainable, high-capacity cathodes (255 mAh g⁻¹ after 150 cycles) and offers new graphite exfoliation and confinement perspectives.
