NOVELTY - Preparation of graphene coated core-shell tin oxide-doped stannous oxide material involves dissolving 40 mg of graphene oxide and 2 mmol of soluble tin salt in 100 mL of deionized water and ultrasonically disperse for 30-60 minutes, and marking as suspension (A), adding 4-6 M strong base to the above solution (A), magnetically stirring uniformly for 10-30 minutes, and marking as suspension (B), adding 1 g of weak reducing agent to the above suspension (B), magnetically stirring for 30-60 minute, centrifuging, and washing with deionized water and ethanol several times to obtain product (C), dispersing product (C) in 100 mL of 15% hydrogen peroxide, magnetically stirring for 6-10 hour, then centrifuging and drying at 60-80 degrees C for 0.5-2 hour to obtain the final product. USE - Preparation of graphene coated core-shell tin oxide-doped stannous oxide material used for anode material for lithium battery (all claimed). ADVANTAGE - The method is environmentally-friendly, and enables preparation of graphene coated core-shell tin oxide-doped stannous oxide material with improved specific capacity during the cycle process of the lithium ion battery, excellent electrochemical performance and reduced energy consumption.
