Abstract

The lithiation of molybdenum disulfide (MoS2) has been directly studied in situ in the TEM by observing specimens with the viewing direction parallel to the basal planes. The MoS2 lamella was characterized by bright-field imaging during the lithiation, and both selected-area diffraction and high-resolution imaging before and after. An overall expansion of ∼5% along the c-direction was observed with concurrent local contraction. The contraction can be related to the expulsion of Mo as Li reduces it to form Li2S.
