(a) Schematic lattice of spinel Li4 viewed from the [110] zone axis, where the Ti, O, Li (8a-sites) and Li (16c-sites) columns are highlighted with light blue, red, green and yellow, respectively. (b) HAADF, ABF images and ABF line profile for Li4 phase. (c) The sample at the first fully discharged state with the Li7 phase and (d) Mg4Li phase. (e) The sample at the first half-charged state and (f) the sample at the first fully charged state. Note that the image contrast of the dark dots is inverted and displayed as peaks in the ABF line profile. Scale bar equals 0.5 nm.
