· Li4 Cu4 P4 O16

Li₄Cu₄P₄O₁₆ is a mixed-metal phosphate compound combining lithium, copper, and phosphorus in an oxide framework, classified as a semiconductor material. This compound belongs to the family of lithium-copper phosphates, which are primarily of research interest for energy storage and electrochemical applications rather than established industrial use. The material's potential lies in solid-state battery electrolytes, ion-conducting ceramics, and electronic device applications where the combination of lithium mobility and copper redox activity may offer advantages over conventional single-metal phosphate systems.
