🔋 Improving the Calendar Life of Silicon Anodes with Inorganic Solid–Electrolyte Interphases

📝 الکترولیت LSCE با نمک مخلوط، SEI عمدتاً معدنی روی آند سیلیکونی تشکیل می‌دهد و پس از پنج ماه ۴۴٪ ظرفیت اولیه را حفظ می‌کند، در حالی که الکترولیت کربناته تنها ۱٪ باقی می‌ماند.

💡 Novelty & Significance:
This study uniquely contrasts calendar aging in single- and mixed-salt locally superconcentrated electrolytes versus carbonate electrolytes, showing mixed-salt LSCEs form predominantly inorganic SEIs that dramatically extend silicon anode calendar life (96% vs. 77% capacity after one month). It identifies SEI reinforcement via controlled anion/solvent redox as a key strategy, offering significant guidance for durable high-energy silicon anode batteries.
