Extended Data Fig. 4: Additional ADF-STEM images.
From: Trapped O2 and the origin of voltage fade in layered Li-rich cathodes

(a) Pristine, (b) 2nd cycle and (c) 100th cycle. Again, well defined atomic layers can be seen within the grains in the pristine and 2nd cycles, while the images from the 100th cycle highlight the presence of voids.
