Oxide-type solid state electrolytes are considered to be a promising solid state electrolyte in all solid state batteries due to their relatively high ionic conductivity, wide potential window, and excellent thermal stability. However, many issues associated with their practical applications in all solid state batteries have yet to be solved, and their underlying mechanisms have not been fully understood. Thus, advanced techniques are called on to analyse these issues. Solid state nuclear magnetic resonance (ssNMR), with its ability to probe local structure, to track ionic motion in different length/time scales, to study lithium/sodium dendrites, and to investigate interfacial issues, has unique advantages in characterizing such oxide-type solid state batteries. In this chapter, we first summarize the state-of-the art applications of ssNMR in the oxide-type solid state batteries mainly including garnet-type and NASICON-type. After that, we also present some perspectives on the employment of ssNMR in oxide-type solid state batteries.
