We additionally mixed samples with added sulfur and iodine using high-energy ball milling for 0.5–1 h. We ground samples in a mortar and pestle to remove large agglomerations after ball milling, and then added DMF (if used). For each experiment, we loaded the mixture into a 10 mm-diameter, hardened-steel die, working in the glovebox.
