🔋 Site‐Selective Anion‐Cation Regulation of Sulfide Electrolyte Enables Low‐Pressure Dendrite‐Suppressed All‐Solid‐State Lithium Metal Batteries

📝 این مقاله با تنظیم آنیون-کاتیون موضعی در الکترولیت سولفیدی Li6PS5Cl، باتری تمام‌حالت‌جامد لیتیوم-فلز با سرکوب دندریت در فشار پایین را ممکن می‌سازد.

💡 Novelty & Significance:
Site-selective Al³⁺/F⁻/Cl⁻ co-regulation of Li₆PS₅Cl stabilizes the sulfide framework and redirects interfacial decomposition toward a LiF/LiCl-rich, Li₂S-poor interphase with strong Li adhesion. This enables 7.22 mS cm⁻¹ conductivity, 8000 h dendrite-free cycling at 3 MPa, and stable NCM811/sulfur full cells at 30 MPa—advancing low-pressure all-solid-state Li metal batteries.
