Figure 5

(a) SR-XRD profiles of the Li1.2Ni0.2Mn0.6O2 electrode at the 1st, 2nd, and 20th cycles. The strongest 001 diffraction peak is enlarged in the inset. (b) Evolution of the a and c lattice parameters and (c) TM and O occupancies for the pristine, 1st, 2nd, and 20th discharged samples. Error bars in (b,c) indicate the standard uncertainties (±3σ) derived from the Rietveld refinements (smaller than the symbols in most cases).
