NOVELTY - Preparing graphene loaded carbon coated tin-antimony lithium battery negative electrode involves putting graphene and fullerene into a solvent, subjecting to ultrasonic dispersion makes it form a uniform mixed solution, using tin source and antimony source as auxiliary materials, crushing the auxiliary materials, dissolving the tin source and antimony source auxiliary materials in N-methylpyrrolidone to obtain N-methylpyrrolidone solution of the tin source and antimony source, dissolving the prepared tin source and antimony source N-methylpyrrolidone solution. The methylpyrrolidone solution is poured into the mixed solution and stirred to obtain a mixed slurry, placed the mixed slurry into a freeze dryer to form mixed powder, placed the mixed powder into the atomizer. USE - Method for preparing graphene loaded carbon coated tin-antimony lithium battery negative electrode. ADVANTAGE - The method has high charging and discharging efficiency, high specific capacity, solves the problem that the carbon in the actual preparation of lithium battery negative electrode not reversible capacity loss is large, and low the specific capacity. DETAILED DESCRIPTION - Preparing graphene loaded carbon coated tin-antimony lithium battery negative electrode involves putting graphene and fullerene into a solvent, subjecting to ultrasonic dispersion makes it form a uniform mixed solution, using tin source and antimony source as auxiliary materials, crushing the auxiliary materials, dissolving the tin source and antimony source auxiliary materials in N-methylpyrrolidone to obtain N-methylpyrrolidone solution of the tin source and antimony source, dissolving the prepared tin source and antimony source N-methylpyrrolidone solution. The methylpyrrolidone solution is poured into the mixed solution and stirred to obtain a mixed slurry, placed the mixed slurry into a freeze dryer to form mixed powder, placed the mixed powder into the atomizer, then loaded argon gas, so that the argon gas forms a uniform coating layer on the surface of the mixed powder to form a precursor, placed the precursor into the mold of the press, molded to obtain a green body. The green body is placed into a dryer for drying to obtain product.
