Abstract

In-Situ CyclingIn article number 2100891, Demortiére and co-workers demonstrate that in-situ cycling of a LiMn1.5Ni0.5O4 thin-film cathode in an electrochemical transmission electron microscope (TEM) holder reveals structural and morphologic changes upon (de)lithiation processes. (S)TEM images of the cycled thin-film reveal the formation of voids, cracks, and organic decomposition products. The 4D STEM ASTAR technique highlights the emergence of an amorphization process in the in-situ cycled electrode.
