Figure 4
3D chemical mapping of the LCO particles in pristine and charged states using peak energy as the descriptor. Panels (a) and (b) show the chemical distribution of the pristine and charged LCO particles. Panel (c) is the representative multi-pixel averaged Co K-edge XANES spectra based on 3D XANES peak-energy maps. Panel (d) is the histogram of the peak energy's distribution. |
