(a) A contour plot of the LiFePO4–FePO4 synchrotron operando data in the 11.5–30.0° 2θ range. (b) Evolution of the weight fractions (in wt%) of LiFePO4 (orange) and FePO4 (blue) phases resulting from the automatic sequential Rietveld refinements. (c) Results of the calculated profiles with the individual contributions of the phases of the tenth pattern in the sequence. The experimental X-ray powder diffraction pattern (blue curve) is compared with the calculated profile (red line). The black line denotes the difference curve between them and green vertical lines indicate the Bragg reflections corresponding to LiFePO4 and FePO4. Green, violet and purple patterns correspond to the individual calculated profiles of LiFePO4, FePO4 and Al, respectively. Note that the few unindexed peaks in the 12–16° 2θ range are due to other cell components and were not included in the refinement.
