Lithium Intercalation in Cubic TiS(2).

Layered transition metal dichalcogenides have been the subject of extensive research in recent years in areas as diverse as superconductivity, charge density waves, and lithium battery electrode materials. TiS(2) has now been synthesized in a three dimensional cubic defect spinel structure (c-TiS(2) by oxidation of the high temperature, stable spinel CuTi(2)S (4) with Br(2) at room temperature. This memo compares Li intercalation in c-TiS(2) and the layered TiS(2). Both form homogeneous single phase series Li(x)TiS(2) for 0 x 1. It is suggested that Li occupies octahedral sites in c-Li (x)TiS(2) as it does for the corresponding c-LiTi0(2).
