Evolution of LiNi0.6Mn0.2Co0.2O2 charged to 4.7 V during heating. a In situ X-ray diffraction (XRD) measurements. bd Direct high angle annular dark field (HAADF) observation of the inner bulk degradation at gradually increased magnifications, enabled by focus ion beam (FIB) milled cross-section sample. The yellow square region in (b) is enlarged as (c) and the yellow square region in (c) is enlarged as (d). The scale bars are 200 nm in (b), 50 nm in (c), and 2 nm in (d)
