💡 Novelty & Significance:
The novelty lies in using a NaNO₃-DMSO additive to build a LiF/NaF–N-rich interphase via dual-ion synergy, preserving carbonate solvation while enabling early anion reduction. This stabilizes silicon-carbon anodes, delivering 1000-cycle durability and 85–95% capacity retention in full cells. It offers a practical strategy for durable Si-based lithium-ion batteries.
