Figure 3

(a) Powder XRD patterns of LiCoO2, De-LiCoO2 and Li0.5CoO2 (the XRD pattern of Li0.5CoO2 was refined by the lattice parameters in ref. 22). (b) Localized XRD patterns with the 2θ range from 15–21°. (c) Localized XRD patterns of De-LiCoO2 loaded on a current collector before (black line) and after (red line) holding at 1.8 V versus reversible hydrogen electrode (RHE) for >2 h. (d) Localized XRD patterns of LiCoO2 loaded on a current collector before (black line) and after (red line) holding at 1.8 V versus RHE for >2 h.
