Boundary region between LiFePO4 and FePO4 after chemical delithiation. a, b Low-magnification BF STEM images of a (010) surface (a) after and (b) before delithiation. Subscript “o” refers to the orthorhombic structure. Scale bar, 500 nm. c ADF STEM image of a section of the surface in a. Scale bar, 100 nm. d Li concentration map from the same region as c. Scale bar, 100 nm. e Magnified Li concentration map of circled region in d. Scale bar, 50 nm
