· Li4 Cu4 F12

Li₄Cu₄F₁₂ is a mixed-metal fluoride compound combining lithium and copper in a structured ionic lattice, belonging to the family of metal fluorides investigated for electrochemical and solid-state applications. This material is primarily of research interest rather than widespread industrial production, with potential applications in solid-state electrolytes, ion-conducting ceramics, and advanced battery systems where lithium-ion transport and thermal stability are critical. The copper-fluoride framework may offer advantages in tailoring ionic conductivity and chemical stability compared to conventional lithium-based ceramic electrolytes.
