a X-ray diffraction (XRD) patterns of liquid-phase-synthesized xLi2S–LiI (x = 1, 3, 5), Li2S, and LiI. b Lattice parameters based on Rietveld refinement of data shown in Supplementary Fig. 3. c Arrhenius plots of Li2S, LiI, and 3Li2S–LiI constructed using AC electrochemical impedance spectroscopy (EIS) data at different temperatures. d Total density of states (DOS) and (e) crystal orbital Hamilton population (COHP) analyses of Li2S and xLi2S–LiI based on first-principles density functional theory (DFT) calculations. The perpendicular dashed line at 0 eV denotes the Fermi level.
