· Li2 Cu2 F7

Li₂Cu₂F₇ is an experimental lithium-copper fluoride compound, a mixed-metal fluoride that belongs to the family of inorganic fluorides being investigated for energy storage and solid-state ionic applications. This material is primarily of research interest rather than established industrial production; it is studied for potential use as a solid electrolyte component or cathode additive in advanced lithium-ion and lithium metal battery systems, where fluoride-based ionic conductors offer advantages in thermal stability and ionic mobility compared to conventional organic electrolytes.
