Cover Story: The phase evolution of Li-rich Li-Mn-Ni-(Al)-O cathode materials upon heat treatments was studied by X-ray and neutron powder diffraction. For two-phase mixtures containing a monoclinic Li2MnO3 type phase M and a rhombohedral LiMn0.5Ni0.5O2 type phase R, the structures, compositions, and phase fractions change with heat treatment time, realized by the substitution mechanism 3Ni2+ ↔ 2Li+ + 1Mn4+. Sample peak broadening is dominated by strain broadening. The X-ray domain sizes of M and R increase with heat treatment time and are larger than the sizes observed by electron microscopy. The domain size is smaller for R than for M and decreases with increasing Al doping. View this paper
