· Li4 Cu4 F14

Li₄Cu₄F₁₄ is a mixed-metal lithium fluoride compound belonging to the class of inorganic ionic semiconductors, combining lithium and copper cations in a fluoride matrix. This is a research-phase material primarily investigated for solid-state battery electrolytes and ionic conductivity applications, where the dual-cation framework aims to achieve enhanced lithium-ion transport while maintaining chemical stability. The material represents an exploratory strategy in the lithium-ion conductor family, with potential advantages over single-cation fluoride electrolytes due to the synergistic ionic transport behavior of the copper-lithium interaction, though industrial deployment remains limited.
