NOVELTY - Preparing reduced graphene/amination column (5) arene/sulfur involves taking graphene oxide solution and adding 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride salt and N-hydroxysuccinimide, stirring for more than 30 minutes, and then adding amination column (5) aromatic hydrocarbon, stirring for 0.5-1 hours, raising temperature to certain temperature and keeping constant, then taking reaction product and dialyzing to obtain GO-AP(5) supramolecular graphene composite material. The reduced graphene/amination column (5) aromatic hydrocarbon/sulfur is used as lithium-sulfur cathode material. The ascorbic acid is added as reducing agent to the obtained GO-AP(5) supramolecular graphene composite material, and stirred at room temperature for more than 2 hours. The concentrated hydrochloric acid is added, and sodium thiosulfate aqueous solution is added dropwise, slowly stirred for more than 6 hours. USE - Method for preparing reduced graphene/amination column arene/sulfur as lithium-sulfur cathode material. ADVANTAGE - The method enables to prepare reduced graphene/amination column arene/sulfur that has high capacity, good rate and long cycle life.

The concentrated hydrochloric acid is added, and sodium thiosulfate aqueous solution is added dropwise, slowly stirred for more than 6 hours. The concentrated hydrochloric acid and sodium thiosulfate are reacted to generate elemental sulfur, and liquid is collected and centrifuged to obtain cathode material.
