Intercalation of Li into Single Crystals of MoS 2

In this paper we study in situ the intercalation of Li across and along the van der Waals planes of MoS 2 single crystals. Li is intercalated according to the band model. The intercalation reaction is inhibited by a Li-S interaction. This interaction is negligible when Li is deposited along the van der Waals planes. The dominance of the intercalation reaction of Li into MoS 2 is dependent on the flux of the deposited Li and the substrate temperature.
