Solid state lithium metal batteries have extremely high safety, due to the non-flammable and non-volatile characteristics, which makes it possible to use high energy density lithium metal as negative electrode. However, there are still several challenges in the industrialization of solid state lithium metal batteries, such as high interface impedance, poor solid electrolyte/electrode compatibility, low electrolyte ionic conductivity and narrow electrochemical window. Therefore, the development of flexible solid electrolytes with high performance has become an important research topic, in terms of accelerating the development of solid state lithium metal batteries. Here, the latest research progress of composite solid electrolytes in solid state lithium metal batteries and the interface problems and solutions of composite solid electrolyte matching electrode materials will be comprehensively described.
