· NaTi5Se8

NaTi5Se8 is an intermetallic compound combining sodium, titanium, and selenium elements, belonging to the layered metal chalcogenide family. This material is primarily of research interest rather than established industrial production, studied for its potential in energy storage and solid-state electronic applications where the combination of metallic titanium with selenium's semiconducting properties offers interesting electrochemical behavior. The material's layered structure and mixed-valence character make it a candidate for battery cathodes, ion conductors, or thermoelectric devices, though commercial deployment remains limited and further development is needed to assess its viability against conventional alternatives.
