🔋 In Situ Formation of a Hybrid Alloy‐Fluoride Interphase for Stable High‐Capacity Phosphorus Anodes
📝 دوپینگ SbF3 در کامپوزیت فسفر-کربن، فاز میانی هیبریدی Li3Sb/LiF را درجا تشکیل میدهد که پایداری و سینتیک آند فسفر در باتری لیتیوم-یون را بهبود میبخشد.

💡 Novelty & Significance:
Trace SbF3 doping in P/C anodes forms an in situ Li3Sb-LiF hybrid interphase during lithiation, simultaneously suppressing polyphosphide shuttling and combining fast ion/electron transport with mechanical rigidity. This resolves the stability-transport trade-off, delivering 970 mAh g⁻¹ after 500 cycles and 893 mAh g⁻¹ at 15 A g⁻¹, with practical pouch-cell validation.
