Figure 3. Sliced analysis of partially charged LiFePO4.

Figure 3

(a) Sliced view of LiFePO4 at highly delithitated state. The sliced view reveals 3D internal core-shell phase distribution. (b) Cross-sectional slides and the corresponding XANES spectra along vertical axis. The spectra indicate the phase is either LiFePO4 or FePO4. (c) Line profile of XANES spectra along the horizontal axis at the selected cross-section slide. The spectra also indicated the chemical composition is either single LiFePO4 or FePO4 phase. Scale bar, 10 μm.
