· JVASP-42828· Li7FeO4F2

Li7FeO4F2 is an experimental lithium iron oxide fluoride ceramic compound that belongs to the family of mixed-anion ceramics combining oxide and fluoride chemistry. This material is primarily of research interest for solid-state battery applications, where lithium-conducting ceramics serve as electrolyte materials, offering potential advantages in ionic conductivity and electrochemical stability compared to conventional oxide or sulfide electrolytes. The inclusion of fluoride anions can enhance lithium-ion transport pathways, making this composition notable in the development of all-solid-state battery systems where high energy density and improved safety are critical design goals.
