Figure 2. Top-view and cross-sectional SEM micrographs of pristine (fresh) NCM88 electrodes (A, D, G, and J) and NCM88 electrodes after 200 cycles at 0.3 C-rate in LP30 (B, E, H, and K) and ILE (C, F, I, and L). The electrodes shown in (A-I) were pressed at 8 t cm2, while those shown in (J-L) are unpressed electrodes. This figure is quoted with permission from Wu et al.[76]. Copyright (2021) The Author(s).
