Figure 8
(a) RGB image of a large (about 1 mm × 5 mm) region of a LiNi0.5Mn1.5O4 electrode charged to 4.783 V with Ni (red), Mn (green) and transmission (blue). (b, c) Relative intensity maps of Mn and Ni from the selected region marked in (a), 0.5 mm × 0.5 mm in size, selected for XANES mapping. (d) Phase distribution of the Ni oxidation state in the selected region obtained by linear combination (LC) fitting. (e) Single-pixel XANES at the selected spots marked in (d) and the correlated LC fit. Adapted from Boesenberg et al. (2015 ![]() ![]() |
