Yingchun Cheng,Anmin Nie,Qingyun Zhang,Li-Yong Gan,Reza Shahbazian-Yassar,Udo Schwingenschlögl +5 more
TL;DR: In situ transmission electron microscopy finds that H- MoS2 transforms to T-LiMoS2 at the early stages of lithiation followed by the formation of Mo and Li2S phases, which is essential for the development of two-dimensional semiconductor-metal contacts based on MoS1 and the usage of MoS 2 as anode material in Li ion batteries.
