NOVELTY - Preparing graphene oxide coating artificial graphite lithium-ion cathode material, comprises (i) adding 45-60 g artificial graphite powder into 10-20 ml n-butanol, and stirring at 50-150 revolution per minute for 1-2 hours minute to obtain solution A, (ii) dissolving 0.1-0.3 g graphene oxide and 0.3-0.6 g polyvinyl alcohol 1788 type in 70-85 ml deionized water, stirring for 15-30 minutes, mixing the obtained mixed solution with solution A, and stirring at 50-150 revolution per minute for 20-30 hours, (iii) adding the suspension obtained in step (ii) into a blast drying oven at 100-150degrees Celsius for 20-30 hours, (iv) taking out the dried sample and adding into a corundum crucible, raising it to 1100-1300degrees Celsius at a heating rate of 3-6degrees Celsius/minute in high-purity nitrogen atmosphere, and maintaining in constant temperature for 1-3 hours, (v) cooling, taking out the sample and grinding to 200-mesh standard screen to obtain final product. USE - The method is useful for preparing graphene oxide coating artificial graphite lithium-ion cathode material. ADVANTAGE - The method: simplifies preparation process. The graphene oxide-coated artificial graphite lithium ion cathode material can be produced on a large scale after being stirred for a long time and treated at a high temperature.
