Fig. 2: Structure and Li+ ion migration pathways.

2D SAXS patterns of a CuMH and b Li-CuMH samples. c Electrostatic potential (ESP) distribution of the CuMH unit. Energy profiles of d 1D, e 2D and f 3D possible Li+ ion migration pathways in Li-CuMH. g The most favorable Li+ migration pathway along the [010] direction of the b-axis, viewed as the light purple isosurface of constant EBVSE(Li) superimposed on the crystal structure.
