NOVELTY - Preparation of aqueous polyaniline positive pole material for lithium-sulfur battery, involves adding graphene oxide and aqueous polyaniline nanofiber powder to obtain a mixed solution (A), adding aqueous sodium thiosulfate solution to the mixed solution (A) and again adding hydrochloric acid to the reaction to obtain a mixed solution (B), and adding hydroiodic acid to the mixed solution (B) to obtain an aqueous polyaniline positive pole material for lithium-sulfur battery. USE - Preparation of aqueous polyaniline positive pole material for lithium-sulfur battery (claimed). ADVANTAGE - The aqueous polyaniline positive pole material has good dispersion in water. The charge-discharge specific capacitance of the battery is 455-865 mAh/g. The charging and discharging capacity holding ratio of the battery after 100 circulation time is 24-31%.
