· Na4 Se4

Na₄Se₄ is an inorganic semiconductor compound composed of sodium and selenium, belonging to the family of alkali metal chalcogenides. This is primarily a research-phase material studied for its electronic and ionic transport properties rather than an established commercial product. The compound shows potential in solid-state battery applications, particularly as a superionic conductor or electrolyte material, due to the high mobility of sodium ions through its crystal structure—making it relevant to next-generation energy storage systems where sodium-ion chemistries offer cost and sustainability advantages over lithium alternatives.
