Figure 1. The SEM images of (A) HR-precursors and (B) LR-precursor particles (insert: the enlarged view). The sXRD Rietveld refinement patterns against (C) HR-NCM and (D) LR-NCM powder samples, the inserts are corresponding SEM images of HR-NCM and LR-NCM. The statistical diagram of primary particle sizes: (E) HR-NCM and (F) LR-NCM (insert: the statistical analysis of primary particle length/width ratio). (G) HR-TEM image of HR-NCM. The insert is the corresponding HRTEM image showing a lattice spacing of 0.47 nm for the layered (003) planes.
