C60-Inorganic fluorides intercalation compounds: some formation condition data and their electrochemical behavior in lithium cell systems

An overview of our contribution to the worldwide work on fluorinated carbons and inorganic fluorides-based intercalation compounds is presented. Recent results concerning the intercalation of NbF5, TaF5 and TiF4 into the C60 lattice and the behavior of a wide series of C60(MFn)x phases used as cathode materials in lithium batteries are described.
