In Situ Solid Electrolyte Ionic Pathway Formation in High Sulfur Loading Cathodes for High‐Performance All‐Solid‐State Lithium–Sulfur Batteries (Adv. Energy Mater. 22/2025)

Lithium–Sulfur Batteries

In article number 2500363, Yuegang Zhang and co-workers improved the performance of all-solid-state lithium-sulfur batteries (ASSLSB), by using a melt-infiltration method to introduce P₂S₅ into sulfur-carbon secondary particles, forming in-situ lithium phosphorus sulfide solid electrolyte during discharging process. This establishes the ionic pathways in the cathode and activates more active materials, enabling high capacity and stable cycling under high sulfur loading, highlighting its potential for advanced ASSLSBs.
