Abstract: The development history of glass-ceramic solid-state electrolyte was comprehensively reviewed, while the basic structure and ion conduction mechanism of NASICON-type (Na+ superionic conductor) materials were elaborated. The latest achievements in NASICON-type glass-ceramic solid electrolytes were summarized, focusing on sodium ion and lithium ion conductive glass-ceramic electrolytes. The structure and performance evolution of the solid electrolytes were described, whereas the limitation of the materials was discussed and the strategies of performance improvement were proposed. In addition, the applications of several NASICON-type glass-ceramic electrolytes in batteries were presented, so as to provide a guidance for the development of new solid electrolytes with high performances.

Key words: NASICON material; fast ion conductor; glass-ceramic electrolyte; solid state battery
