Figure 3: XAS spectra of Li₂MoO₃ during the first charge.

(a) In situ XANES spectra at Mo K-edge during charging to 4.8 V. (b) Ex situ FT-EXAFS spectra of Li_2−xMoO₃ at pristine (x=0), half charged (x=0.75) and fully charged (x=1.47) states. The lower panel shows the FT-EXAFS spectra of MoO₂ and a-MoO₃ references.
