Oxygen to reduced oxygen species conversion (a) and Li:C ratio (b) vs oxygen exposure dose for lithiated MLG (green) and CNW (red). α was calculated as α = (I ā€“ Imin)/(Imax ā€“ Imin), where I, Imin, and Imax correspond to O 1s peak integral intensity at the current exposure point, at the beginning, and at the end of oxygen exposure, respectively. Dotted lines are shown for eye guidance. (cā€“f) Maps of the background signal intensity (c, e) associated with morphology and of the background-corrected Li 1s intensity (d, f), which represents reaction product distribution of oxygen exposed lithiated MLG (c, d) and CNW (e, f) samples.
