· Li2 Cu2 F6

Li₂Cu₂F₆ is an inorganic fluoride compound combining lithium and copper in a layered crystal structure, classified as a semiconductor material with potential ionic conduction properties. This compound is primarily of research and development interest rather than established industrial production, belonging to the family of mixed-metal fluorides being investigated for solid-state electrolytes, energy storage, and advanced electronic devices. The combination of lithium's ionic mobility and copper's variable oxidation states makes this material notable for potential applications in next-generation lithium-ion batteries and fluoride-based solid-state conductors where alternatives like oxide ceramics face limitations.
