Fig. 4: TEM characterization of pristine O3 NaNi0.4Mn0.4Co0.2O2.
From: Native lattice strain induced structural earthquake in sodium layered oxide cathodes
a Low and b high magnification, c high-resolution bright-field TEM image, d SAED pattern, e GPA analysis and f atomic structural model of the strained O3 NaNi0.4Mn0.4Co0.2O2. Inset in c is the zoomed-in view of the region marked by a white square. The color in c represents the intensity, with red for highest and blue for lowest. \(\theta\) is the angle between layered direction and strain direction. The yellow, red, blue, gray, and purple spheres in f represent Na, O, Ni, Co, and Mn atoms, respectively.
