Figure 8
XRD patterns evolution following ethylmethylimidazolium intercalation and de-intercalation into/from graphite. All indicated potentials are versus Li/Li+. The potential scan starts from 3 V for the bottom pattern, decreases to 0.5 V for the middle one, and goes back to 3 V for the top-most pattern. The counter electrode is activated carbon, the electrolyte is ethylene carbonate:dimethyl carbonate (1:1) with 1 M LiPF6.
