Fig. 3 — In situ heating-induced crack nucleation and propagation. The LiNi_0.6Mn_0.2Co_0.2O₂ (NMC622) was delithiated by charging to 4.7 V vs. Li metal. a and b High angle annular dark field (HAADF) images from delithiated NMC622 before heating (room temperature). c–f HAADF images after heating to 275 °C. Selected area electron diffraction (SAED) patterns and fast Fourier transformation images in (a), (c), and (e) show the overall lattice change during heating. d, e, and f show local lattice structure change at crack regions and crack-free regions. The scale bars are 200 nm in (a) and (c); 10 nm in (b) and (d); and 4 nm in (e) and (f)
