· JVASP-27530· Na6ZnS4

Na₆ZnS₄ is an ionic ceramic compound belonging to the sulfide ceramic family, combining sodium, zinc, and sulfur in a fixed stoichiometric ratio. This material is primarily of research interest for solid-state ionics and energy storage applications, particularly as a potential superionic conductor or electrolyte material in advanced battery systems. Its notable characteristic is the combination of alkali metal (sodium) and transition metal (zinc) with sulfide anions, which creates the structural framework for potential fast ion transport—a property that makes it relevant to next-generation solid-state battery development where it competes with other sulfide-based solid electrolytes.
