| Abstract: |
Metal fluorides have been considered attractive for a variety of applications due to their particular thermodynamic and ion conducting properties. For electrochemical energy storage their high enthalpy of formation and their relatively high density makes metal fluorides interesting as cathode materials. Moreover, fast fluoride ion conducting materials have been utilized in solid-state electrochemical devices such as solid-state batteries, fuel cells, sensors and electrochromic displays. In sensors, fluorides have been used for sensing various physical and chemical parameters. Recently, it was shown that metal fluorides can also be used as both active materials and solid electrolytes in so-called fluoride ion batteries which are based on reversible anion shuttle. Herein, mechanism of ion conduction in solids, current state of fast fluoride ion conductors based on fluorite and tysonite structures as well as of mixed compounds based on Pb, Sn, Bi and Sb will be reviewed and discussed. The discussion involves recent approaches to further increase the ionic conductivity in particular systems such as nanostructuring and tailoring of grain boundaries. |
