NOVELTY - A tin oxide-graphene aerosol producing method involves preparing graphene oxide water dispersion liquid. Prepared graphene oxide water dispersion liquid is added to concentrated aqueous ammonia water and stirred. Tin source is added to the mixture and stirred. Polyvinyl pyrrolidone is added to mixture, and dispersed ultrasonically. Obtained mixture is transferred to a hydrothermal reactor for performing hydrothermal reaction, dialyzed with ultrapure water and then freeze dried. Freeze-dried sample is dried and heat-treated. USE - Method for producing tin oxide-graphene aerosol used for producing lithium-ion battery cathode (claimed). ADVANTAGE - The method enables producing tin oxide-graphene aerosol with certain toughness, and eliminating usage of conductive agent and binder, thus reducing cost of lithium ion battery and improves assembling technology of battery. DETAILED DESCRIPTION - A tin oxide-graphene aerosol producing method, involves preparing graphene oxide water dispersion liquid with concentration of 0.5-5 mg/ml by Hummers method. 300mg prepared graphene oxide water dispersion liquid is added to 1-3 ml concentrated aqueous ammonia water and stirred uniformly. 0-1 g tin source is added to the mixture and stirred to dissolve completely. 20-100 mg polyvinylpyrrolidone with average molecular weight of 55000 is added to mixture containing 400 mg tin source, and dispersed ultrasonically for 2 hours. Obtained mixture is transferred to a hydrothermal reactor for performing hydrothermal reaction at 100-300 degrees C for 1-24 hours. Obtained sample is dialyzed with ultrapure water for one day and frozen at -20 degrees C for 4 hours, and then freeze dried at -53 degrees C and 30Pa for 12 hours. Freeze-dried sample is dried at 70 degrees C for 10 hours under vacuum and heat-treated at 550 degrees C for 3 hours under argon gas atmosphere. Tin source is chosen from tin tetrachloride, stannous sulfate, stannous chloride, and their mixtures.
