dc.description.abstractThis work presents the first in-situ neutron diffraction study of the MoS2 electrode, undertaken in a custom-built li-ion battery during discharge. A review of custom-designed cells for in-situ neutron diffraction experiments is presented along with our optimised cell, which we use to show real-time information corresponding to Li-insertion into MoS2 via disappearance of the (103) reflection and increase in the d-spacing of the (002) reflection. The changes in the diffraction patterns begin at the 1.1 V plateau and are complete during the 0.5 V plateau. Sequential Rietveld-refinement indicates the presence of an intermediate lithiated phase (LixMoS2) between MoS2 and LiMoS2. We observe the disappearance of all reflections for the MoS2, corresponding to the loss of long-range order, during the 0.5 V plateau and no new diffraction peaks appear with further electrochemical cycling. This result is indicative of a transformation from long-range ordered MoS2 to short-range ordered LiMoS2, a result that we confirm using ex-situ synchrotron X-ray and neutron diffraction. © 2011, Elsevier Ltd.en_AU
