💡 Novelty & Significance:
This work introduces electrostatic regulation of sulfur spatial evolution via BN/CNT heterostructures, separating polar and conductive domains to control polysulfide interactions. Amine functionalization tailors interfacial charge, enabling homogeneous sulfur redistribution and near-zero cathode swelling. The design achieves 1150 mAh g⁻¹ over 500 cycles, establishing a new principle for dimensionally stable Li–S batteries beyond adsorption-centric strategies.
