摘要

Numerous layered structured compounds are interesting materials in which lithium intercalation occurs primarily without destruction of the host lattice. In many cases a rigid band model is a useful first approximation for describing the changes in electronic properties of the host material with intercalation [W.Y. Liang, Mater. Sci. Eng. B 3 (1989) 139]. This review paper presents results obtained on transition-metal chalcogenide compounds and effects of lithium intercalation on transition-metal oxides as well. We observed, nevertheless, that the rigid-band model is not applicable to all of the layered intercalation materials. One may argue that the applicability of the rigid-band model may be taken as a test for the properties most desirable in a good intercalation material. This needs yet to be more extensively documented for their promising applications as insertion electrode in solid state batteries.
