demonstrated by Poizot et al. who used transition-metaloxides as anode materials [9]. Metal fluorides are also prominent examples as they reversibly react with lithium at relatively high voltages so that they can be used as cathode materials [5][8][12][13][14][15][16]. Fluorine is the lightest and smallest

Thermally controlled metal–insulator transitions (MIT) are observed in a large number of crystalline and amorphous semiconductors. Particularly among the transitionmetaloxides, there are numerous
