· Li6 Cu1 S4

Li₆Cu₁S₄ is an experimental mixed-metal sulfide semiconductor compound combining lithium, copper, and sulfur in a fixed stoichiometric ratio. This material belongs to the family of lithium-metal chalcogenides and is primarily of research interest for solid-state ionic and electronic applications rather than established commercial use. The compound's potential lies in solid electrolyte development for next-generation batteries and as a semiconductor for photovoltaic or thermoelectric device research, where the combination of high lithium content and copper's electronic properties may offer advantages over conventional single-component alternatives.
