All reagents, namely sulfur (≥99.5%, Sigma-Aldrich), 1,3-diisopropenylbenzene (DIB, 97%, TCI), sodium carboxymethyl cellulose (CMC, MW 250,000, Sigma-Aldrich), polyacrylic acid (PAA, MW 450,000, Sigma-Aldrich), electrolyte (purchased from E-lyte) consisting of lithium bis(trifluoromethane)sulfonimide and 2 wt% lithium nitrate in a 1:1 v/v mixture of 1,3-dioxolane and 1,2-dimethoxy ethane, metallic lithium chips (99.95%, China Energy Lithium), polypropylene separator (Celgard-2700), and carbon black (super p, Macklin) are used directly. SDIB10 was synthesized using the previously reported method. 10 wt% sulfur is added into a glass vial equipped with a magnetic stir bar and heated to 130 • C in a thermostated oil bath. DIB is added to the fully molten sulfur using a syringe and stirred for 10 minutes to achieve a homogeneous mixture. The resulting mixture is further heated to 185 • C for 8-10 minutes, which results in vitrification of the mixture. The product is then cooled down to room temperature. The obtained product is mixed with carbon black and binder mixture of CMC/PAA (1/1 w/w) in a mass ratio of 75:20:5 in water. The slurry is then ball milled and blade cast onto carbon coated aluminum foil. The areal mass loading of sulfur inside the electrode is around 3 mg/cm 2 . After getting completely dried, the prepared electrode is cut into disks with 12 mm diameters to be used as cathode in a coin cell.
