· Li4 Cu2 Sb2 P4 O16

Li₄Cu₂Sb₂P₄O₁₆ is a mixed-metal phosphate compound belonging to the class of lithium-based inorganic semiconductors, combining copper, antimony, phosphorus, and oxygen in a complex crystalline structure. This material is primarily of research interest for solid-state ionic conductivity and energy storage applications, as compounds in this family are being explored for advanced lithium-ion battery electrolytes and related electrochemical devices. The combination of copper and antimony redox activity with lithium-conducting frameworks makes it a candidate material for next-generation energy storage systems, though it remains largely in the development stage with potential advantages in thermal stability and ionic transport compared to conventional polymer electrolytes.
