💡 Novelty & Significance:
This work pioneers a universal spin-polarization-engineered antibonding-orbital modulation paradigm to weaken robust M─S bonds, overcoming intrinsic kinetic barriers in conversion anodes. Magnetic Mn doping induces a low-to-high spin transition, boosting antibonding electron occupancy. The resulting Mn-FeS₂/CoS₂ anode achieves 300 mAh g⁻¹ at 120 A g⁻¹ and 13,000-cycle stability, validating a general strategy for ultrahigh-rate sodium-ion batteries.
