· JVASP-103445· Na4TeSe

Na4TeSe is an inorganic ceramic compound combining sodium, tellurium, and selenium—a mixed-chalcogenide material belonging to the class of solid electrolytes and ion-conducting ceramics. This compound is primarily of research interest rather than established industrial production, explored for its potential ionic conductivity and structural properties in energy storage and electrochemical device applications. The sodium-rich composition positions it within the family of solid-state electrolyte materials being investigated to enable next-generation battery technologies and other devices requiring fast ion transport at moderate temperatures.
