Figure 1. (A) Rietveld analysis of the synchrotron XRD pattern of Li₈VS_5.5 with R_wp = 3.13%, R_e = 1.64%, and S = 1.91. (B) S K-edge and (C) V K-edge XANES spectra of Li₅VS₄, Li₆VS_4.5, Li₇VS₅, Li₈VS_5.5, and Li₉VS₆ with reference spectra of Li₂S, LiVS₂, and V₂S₃. The V K-edge XANES spectrum of Li₉VS₆ is not shown because of its low S/N ratio.
