Figure 3: The change in anodic lithium during discharge–charge cycling.

(a) Discharge–charge voltage profile of the operando Li–O2 cell as a function of cycling time. The stages at which XRD data sets were collected are marked as i, ii, iii… on the curve. (b) Four representative XRD sets taken at the cycling stage i, iii, vi, and ix; each set consisted of seven selected XRD patterns collected at various anode–separator interfacial depths (marked as 1, 2, … 7 of different colours on the right of each set). (c) An expanded XRD data set at stage ix covering the whole anode through adjacent separator region. The inset is a representative XRD pattern taken from the position marked by a blue line that includes references of Li and LiOH.
