The lithium intercalates of the transition metal dichalcogenides

The lithium intercalation compounds of the layered transition metal dichalcogenides, prepared by reaction with nbutyl lithium, have been characterised by x-ray analysis. The group IVB and VB compounds are stoichiometric and stable; the intercalation proceeds by simple expansion of the lattice at the Van der Waals gap. The group VIB chalcogenides, SnS₂ and ReSe₂ do not form lithium intercalation compounds with the exception of MoS₂ and that appears to be metastable.
