Abstract:

Lithium-ion solid electrolyte is a key material for the development of high-safety solid-state lithium batteries, and its electrochemical performance is closely related to the full batteries. Ionic conductivity, electronic conductivity, electrochemical window, and stability versus lithium interface are the key electrical and electrochemical properties of solid electrolytes. In-depth characterization and analysis can help understand the compatibility between different electrolyte and electrode materials, which facilitates the development of high-performance solid-state lithium batteries. This study introduces different types of lithium-ion solid electrolytes. The key electrochemical performances, methods, principles, and equipment for testing are described. In addition, the analysis of the data is described in combination with specific cases.

Key words: solid electrolytes, conductivity, electrochemical window, interfacial stability, lithium batteries
