· Li4 Cu1 F7

Li4Cu1F7 is a lithium copper fluoride compound belonging to the family of mixed-metal fluorides, which are of significant interest in solid-state ionics and battery research. This is primarily a research material rather than a commercial engineering material; compounds in this family are investigated as potential solid electrolytes and ion-conducting ceramics for next-generation lithium-ion and all-solid-state battery systems. The combination of lithium and fluoride chemistry makes such materials candidates for high ionic conductivity applications where conventional liquid electrolytes present safety, thermal, or volumetric constraints.
