· JVASP-47738· Li2CuF5

Li2CuF5 is an inorganic lithium-copper fluoride compound that belongs to the family of mixed-metal fluorides. This is primarily a research material under investigation for electrochemical and solid-state applications rather than an established commercial material. The compound is notable in battery research contexts, particularly for solid electrolyte and cathode material development in next-generation lithium-ion and solid-state battery systems, where mixed-metal fluorides offer potential advantages in ionic conductivity and electrochemical stability compared to conventional oxide or single-metal fluoride alternatives.
