Extended Data Fig. 10: Structure and property evolution of S9.3I cathode during cycling.
From: Healable and conductive sulfur iodide for solid-state Li–S batteries
(a) XRD of chemically lithiated S9.3I. A chemically lithiated S9.3I particle with a few micrometers (b) and corresponding iodine element mapping (c) shows a uniform iodine distribution. EDX mapping images of S9.3I cathode at different states: (d) Pristine, (e) after 10 cycles and heated over 48 h at 100 °C, and the corresponding element analysis. There is only a very small S: I atomic ratio change after 10 cycles and then heated at 100 °C for over 48 h, indicating the thermal stability of S9.3I cathode. (f) EIS spectra and (g) corresponding DRT analysis of Li-S9.3I full cell at different cycles.
