Formula would be a reaction in pure solid state to introduce a disproportionation of sulfur by the dry grinding. Although not shown here in detailed, experimental results indied that it was not easy to fulfill this solidstate reaction to obtain Bi 2 O 2 S at high yield. Therefore, a small amount of NaOH solution was added to facilitate the sulfur oxidationreduction.
Jan 02, 2018 · Preparation of Sulfur Cathode: Sulfur hode with a content of 60% was prepared by grinding commercial sulfur powder, Super P, and PVDF at a ratio of 6:3:1 in Nmethyl2pyrrolidone (NMP) solvent to form a uniform slurry. Then, the slurry was casted on an aluminum foil and followed by drying at 60 °C before use.
