This research direction focuses on the design and synthesis of highly stable solid electrolytes. For oxide systems, we developed a Ta-doped LLZO hot-pressing sintering technology that maintains excellent stability against air and lithium metal while achieving ionic conductivity surpassing 10-3 S cm-1. An innovative organic/inorganic Lewis acid-base dynamic complexation strategy was proposed to regulate molecular interfacial interactions between organic phases (e.g., polymers or ionic liquids) and inorganic phases (LLZO, sulfides), constructing a three-dimensional lithium-ion transport network across organic phase-interlayer-inorganic phase interfaces, significantly enhancing the room-temperature ionic conductivity of composite electrolytes. Furthermore, a hierarchically structured composite electrolyte with a flexible outer layer encapsulating a rigid inner core was designed to simultaneously address electrode-electrolyte interfacial contact failure and lithium dendrite penetration challenges. For sulfide/halide systems, we combined high-throughput computational screening (DFT and machine learning), high-entropy composition design, and grain boundary engineering to develop novel superionic conductors with high ionic conductivity (>5 mS cm-1) and wide electrochemical stability windows (>4.6 V), providing advanced electrolyte solutions for all-solid-state batteries.
