Fig. 3. Structural stability and lattice oxygen suppression in the post-cycled NCM-MS and NCM. a, c) Cross-sectional SEM images of NCM and NCM-MS after 100 cycles. b, d) TEM and HAADF-STEM images of NCM and NCM-MS. e, g) Wavelet Fourier transform of Mn and Ni in NCM-MS. f, h) Corresponding transforms in NCM. i–l) R-space EXAFS fitting results for NCM-MS and NCM. m, n) Orbital hybridization between Ni–O (in NCM) and Mo–O (in NCM-MS). o) Schematic illustration of decreasing oxygen vacancy formation in NCM-MS. p) Calculated oxygen vacancy formation energies. q–s) DEMS profiles during cycling for demonstrating reduction of oxygen release in the NCM-MS compared with NCM.
