· JVASP-102439· LiHF2

Lithium difluoride (LiHF₂) is an ionic ceramic compound combining lithium with fluoride ions, belonging to the family of lithium halide ceramics. This material is primarily investigated in research contexts for applications requiring high ionic conductivity and chemical stability, particularly in solid-state battery electrolytes and fluoride-ion conducting systems where traditional oxide ceramics are unsuitable. LiHF₂ is notable for its potential to enable next-generation energy storage devices through its superionic properties, though industrial deployment remains limited compared to established ceramic alternatives like yttria-stabilized zirconia or lithium phosphate-based ceramics.
