Cobalt difluoride (CoF₂) is an inorganic metal fluoride compound that functions as a ceramic or ionic solid rather than a traditional metallic material, despite cobalt's metallic nature in other forms. It appears primarily in electrochemistry and solid-state chemistry research, where it serves as a cathode material in lithium-ion batteries and as a precursor in fluoride-based energy storage systems. CoF₂ is notable for its high theoretical capacity and stable crystal structure under cycling, making it of interest to battery researchers seeking alternatives to conventional layered oxide cathodes, though industrial deployment remains limited compared to established materials.
