🔋 Fluorinated Aromatic Diluent Enabling Stable and Non–flammable Phosphate Electrolytes for Sodium Metal Batteries
📝 افزودن 1,2-difluorobenzene به الکترولیت فسفات غلیظ موضعی، با مشارکت در واکنشهای بینسطحی و تشکیل SEI/CEI پایدار، باتری سدیمفلزی غیرقابلاشتعال با پایداری چرخهای بالا فراهم میکند.

💡 Novelty & Significance:
DFB is introduced as a non-inert diluent for phosphate electrolytes, forming a localized high-concentration system. Unlike conventional diluents, DFB participates in interfacial reactions, creating a bilayer SEI and compact CEI. This yields non-flammable, stable sodium metal batteries with 98.95% coulombic efficiency and 85% capacity retention over 250 cycles, advancing safe grid-scale energy storage.
