· Li4 Cu2 F12

Li₄Cu₂F₁₂ is an inorganic lithium-copper fluoride compound under investigation as a solid electrolyte and ion-conducting material for advanced energy storage systems. This material belongs to the family of mixed-metal fluorides being explored in battery research for its potential ionic conductivity and electrochemical stability, though it remains largely in experimental/research phases rather than established production use. Engineers considering this compound would target next-generation lithium-ion or all-solid-state battery architectures where the electrolyte material is critical to performance.
