Fluoride ion batteries are interesting candidates for energy storage applications owing to the highest oxidation potential of F -/F2 redox couple (+2.87 V vs SHE) and thus redox stability of the fluoride ion F -, low atomic mass of F (18.998 g mol ) along with the abundance of fluorine itself . FIBs have the potential of reaching both superior gravimetric and volumetric energy density than LIBs, which is of interest for electric vehicles and other large-scale energy storage applications . Hence, considering F -as a stable ion for the charge transfer in the battery is a viable promising alternative.
