· JVASP-50769· Li3CuF6

Li3CuF6 is a lithium copper fluoride compound belonging to the family of mixed-metal fluorides, which are of significant interest in solid-state electrochemistry and energy storage research. This material is primarily investigated as a solid electrolyte or electrolyte additive for advanced lithium-ion and solid-state battery systems, where fluoride-based compounds offer potential advantages in ionic conductivity and electrochemical stability. Engineers consider lithium fluoride compounds when designing next-generation energy storage devices that require higher energy density, improved thermal stability, and extended cycle life compared to conventional liquid electrolytes.
