· JVASP-50754· Li3CuF5

Li3CuF5 is an inorganic lithium copper fluoride compound that belongs to the class of mixed-metal fluorides, currently under investigation as a solid electrolyte material for advanced battery applications. This is a research-phase compound rather than a commercially mature material, notable for its potential to enable higher energy density and improved safety in solid-state lithium-ion battery systems compared to conventional liquid electrolytes. The combination of lithium and fluoride chemistry positions it within the broader family of inorganic solid electrolytes being developed to overcome thermal and cycling stability limitations of organic polymer electrolytes.
