Figure 3: DFT calculations and STEM-EELS spectra.
From: Discovery of abnormal lithium-storage sites in molybdenum dioxide electrodes
(a) Snapshots of the ordered mesoporous MoO2 electrode with the increase of Li inserted, calculated by DFT, and (b) top-view HRTEM image taken from a fully lithiated ordered mesoporous MoO2, demonstrating the formation of three different phases: crystalline phase (DCP), amorphous phase (DAP) and SEI (DSEI). Scale bar= 5 nm. (c) STEM-EELS spectra taken from areas DCP, DAP and DSEI of the fully lithiated ordered mesoporous MoO2. Dotted lines represent the peak position of Mo N edge (blue) and the onset of Li K-edge (black).
