Due to their high ionic conductivity and adeciduate mechanical features for lamination, sulfide composites have received increasing attention as solid electrolyte in all-solid-state batteries. Their smaller electronegativity and binding energy to Li ions and bigger atomic radius provide high ionic conductivity and make them attractive for practical applications. In recent years, noticeable efforts have been made to develop high-performance sulfide solid-state electrolytes. However, sulfide solid-state electrolytes still face numerous challenges including: 1) the need for a higher stability voltage window, 2) a better electrode-electrolyte interface and air stability, and 3) a cost-effective approach for large-scale manufacturing. Herein, a comprehensive update on the properties (structural and chemical), synthesis of sulfide solid-state electrolytes, and the development of sulfide-based all-solid-state batteries is provided, including electrochemical and chemical stability, interface stabilization, and their applications in high performance and safe energy storage.

基于硫化物的固态电解质：全固态电池的合成，稳定性和潜力。

由于其高的离子电导率和足够的层压机械特性，硫化物复合材料作为全固态电池中的固体电解质越来越受到关注。它们的较小的电负性和与Li离子的结合能以及较大的原子半径可提供较高的离子电导率，使其对实际应用具有吸引力。近年来，在开发高性能硫化物固态电解质方面做出了显着的努力。然而，硫化物固态电解质仍然面临许多挑战，包括：1）需要更高的稳定性电压窗口，2）更好的电极-电解质界面和空气稳定性，以及3）大规模生产的经济有效方法。在此，对特性（结构和化学）进行了全面的更新，
