The detailed morphologies of the Cu/LTO edge: (a) HRTEM image taken of the edge area of Cu/LTO. (b) HRTEM image of a piece of the exposed LTO (111) planes showing a stepped surface. The green circle denotes a defect on the surface. (c) The enlarged (FFT inverse) image of LTO NPs taken from Cu/LTO, where the black holes denote the 16c (vacancy) sites and Li2 represents Li1/3Ti5/3. (d) The corresponding schematic lattice of LTO. Scale bar: 1 nm.
