🔋 Harnessing Anion Perturbation for Self‐Limiting Decomposition for Durable Argyrodite‐Based Solid‐State Lithium Metal Batteries
📝 اختلال آنیونی در الکترولیت آرژیرودیت با فلوروزیرکونات، تشکیل SEI خودمحدودشونده را هدایت و چرخهپذیری باتری لیتیوم-فلز حالت جامد را بهبود میدهد.

💡 Novelty & Significance:
Fluorozirconate incorporation perturbs PS₄³⁻ anions in argyrodite electrolytes, deliberately triggering controlled decomposition to form a self-limiting, Li₂S/LiₓP- and F-rich SEI. This shifts the paradigm from suppressing to harnessing decomposition. The robust, insulating interphase enables 7000 h Li||Li cycling and 81.3% capacity retention after 1200 cycles, offering a facile strategy for durable solid-state lithium metal batteries.
