Figure 4

STEM images of half lithiated Fe2(MoO4)3.

(a) Schematics of Fe2(MoO4)3 and Li2Fe2(MoO4)3 along the [001] projection. (b) ABF-STEM image of partially lithiated Fe2(MoO4)3 at the 1/2 discharge state. Atomic arrangements of Li2Fe2(MoO4)3 and Fe2(MoO4)3 are shown as the insets in the regions 1 and 2, respectively. (c) The corresponding ABF line profile acquired at the purples lines across the boundary (red dash lines) in (b). O sites and Li sites are marked by red and black arrows in the region 1 respectively and the O sites are marked by blue arrows in the region 2.
