a XRD pattern of the Li2S-LiI materials. The pattern is fit with the Rietveld method as implemented in GSAS. The inset represents the cubic structure of Li2S and LiI (space group of Fm3m). b, c, d SEM images, TEM images, and energy spectrum of the Li2S and Li2S-LiI (3:1) materials; e, f S 2p and I 3d XPS depth profiles of the pristine Li2S-LiI (3:1) materials.
