Figure 1. Mechanochemically induced halide segregation in composite chalcogen cathodes. (A) Schematic of mechanically and thermally assisted halide redistribution during ultrahigh-speed (UHS) mixing; (B) High-angle annular dark-field image and elemental maps of a composite S/Li₆PS₅Cl (LPSCl)/C cathode after mixing at 2,000 rpm for 5 h. All scale bars are 500 nm; (C) Cl-to-P atomic ratios in pristine LPSCl and the UHS-mixed composite cathode; (D) Electron energy loss spectra from selected regions of the composite Se/LPSCl/C cathode; (E) Long-term cycling of the optimized S/LPSCl/C cathode at a sulfur loading of 4 mg cm^-2 at room temperature.
