· JVASP-50747· Li5CuF8

Li5CuF8 is a lithium copper fluoride compound that belongs to the family of mixed-metal fluorides, materials of significant interest in electrochemistry and solid-state ionics research. This is an experimental compound studied primarily for its potential as a solid electrolyte material or electrode constituent in advanced lithium-ion and solid-state battery systems, where fluoride-based compounds offer high ionic conductivity and electrochemical stability. Engineers and materials researchers consider such lithium fluoride composites for next-generation energy storage applications where conventional liquid electrolytes present thermal, safety, or performance limitations.
