Figure 3. Contour plots of in situ XRD patterns of (A) HR-NCM and (B) LR-NCM for 003 and 018/110 reflections and the corresponding charge-discharge curves during the initial cycle. Lattice parameters of the (C) c-axis, (D) α-axis, and (E) unit cell volume as a function of the state of charge for both cathodes.
