Figure 2: Crystal structures before and after surface modification.
From: A stable lithium-rich surface structure for lithium-rich layered cathode materials

(a) X-ray diffraction patterns of the pristine electrode and the surface-modified electrode with 5 wt% Li2MnO3. (b,c) HAADF-STEM images of (b) the pristine electrode and (c) the surface-modified electrode with 5 wt% Li2MnO3. b,c were obtained along the rhombohedral [100] and monoclinic [010] directions, respectively. The red, blue and orange circles represent TM (M=Ni, Co and Mn), Ni and Mn, respectively. Scale bars, 5 Å.
