由于其高离子电导率和优异的机械性能，硫化物复合材料作为全固态电池的固体电解质受到越来越多的关注。它们具有较小的电负性和对Li离子的结合能，以及较大的原子半径，因此具有较高的离子导电性，具有较好的实际应用价值。近年来，人们在开发高性能硫化物固态电解质方面做出了显著的努力。然而，硫化物固态电解质仍然面临着许多挑战，包括：1)需要更高的稳定电压窗口，2)更好的电极-电解质界面和空气稳定性，以及3)大规模制造的成本效益方法。本文全面介绍了硫化物固态电解质的性质（结构和化学）、合成以及硫化物基全固态电池的发展，包括电化学和化学稳定性、界面稳定性及其在高性能和安全储能方面的应用。
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.
