《Li7P3S11 Electrolyte: Synthesis, Conduction, and Application》
Exploring solid electrolytes with high ion conductivity, good chemical/electrochemical stability, and excellent electrode compatibility is crucial for developing solid-state batteries. Compared with other solid electrolytes, sulfide solid electrolytes possess the advantages of high ionic conductivity and good mechanical processing performance and are expected to be one of the most promising practical solid electrolytes. Among sulfide electrolytes, Li7P3S11 is highly attractive due to its high ionic conductivity and lower raw material costs. In this review, the structure, Li+ conduction mechanism, and synthetic routes of Li7P3S11 electrolyte are described firstly. Then, the current modification strategies utilized to improve the ionic conductivity, air/water stability, and electrochemical stability are recapped, and the applications of Li7P3S11 electrolyte both in solid-state lithium-sulfur batteries and solid-state batteries with commercial cathode materials are systematically summarized. Finally, the challenges and the development trend for Li7P3S11 electrolyte and its applications are provided.
