Figure 1: In situ XRD of Li2MoO3 during the first charge.

(a) The XRD pattern of the Li2−xMoO3 electrode right after charging to 4.8 V. (b) Contour plot of diffraction peak evolution of (003), (101), (104), (107), (108) and (110) during delithiation. (c) The XRD pattern of the Li2MoO3 electrode before charge. (d) Charge curve at a current density of 10 mA g−1 from open circuit voltage (OCV) to 4.8 V during XRD data collection.
