Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

Advanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Development of a Solid‐Liquid Hybrid Electrolyte Composed of LiTa2PO8 and [C2mim][FSA]–Li[FSA] Ionic Liquid for Rechargeable Lithium Metal Batteries

Advanced Materials Interfaces, EarlyView.
LiTa2PO8 (LTPO) suffers from high interfacial resistance when paired with Li metal due to poor solid‐solid contact. Coating LTPO with an ionic liquid (IL) markedly improves interfacial stability, maintaining favorable resistance up to 2000 cycles. However, contact between IL‐coated LTPO and Li metal induces discoloration of LTPO, which is attributed to
