💡 Novelty & Significance:
The novelty lies in molecular-cavity engineering using cyclic precursors (β-cyclodextrin) to create topology-derived intrinsic closed pores in hard carbon, enabling precise pore regulation. Significance: β-ICHC achieves 410.2 mAh g⁻¹ capacity, 94.7% ICE, and 99.7% retention over 300 cycles, with sub-0.35 nm sieving pores boosting capacity and ICE while pseudo-graphitic walls enable fast Na⁺ transport, revealing a three-stage storage mechanism.
