Figure 2

(a) SR-XRD profiles of the Li1.2Ni0.2Mn0.6O2 electrode at the 1st cycle. The strongest 001 diffraction peak was indexed with C2/m and is enlarged in the inset. The sample numbers are described in Fig. 1. (b) Evolution of the a and c lattice parameters and (c) TM and O occupancies during the 1st cycle. Error bars in (b,c) indicate the standard uncertainties (±3σ) derived from the Rietveld refinements (smaller than the symbols in most cases).
