NOVELTY - A process for graphene-coated needle coke powder, comprising the following steps: (1) heating 8-12μm needle coke powder in a mixing pot, with temperature controlled at 120-130℃, and continuously stirring to ensure uniform heating of the needle coke powder; (2) controlling the heating temperature in segments, spraying 0.5-1 g/l graphene aqueous solution onto the needle coke powder in multiple batches, while continuously stirring; (3) after dehydration is completed, cooling to room temperature to obtain graphene-coated needle coke powder, which is bagged and sealed for storage. USE - The method is useful for coating needle-shaped coke graphene, which is useful in lithium ion battery industry. The graphene is useful as electrode material for energy storage of negative electrode material is one of four key material lithium the ion battery. ADVANTAGE - The invention uniformly sprays the graphene solution into the needle coke powder with high temperature for many times, the mixing is more uniform, the coating effect is good, the heating temperature is slowly improved, and the earlier temperature is slightly lower, the water will not be discharged quickly, it is good for ensuring safety. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for graphene the needle-shaped coke powder. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the graphene needle-shaped coke powder process of the device. 1Kneading pot 2Cover 3Relief valve 4Spraying pipe 5Spraying head 6Conveying pipe 7Liquid storage tank 8Spraying pump 9Quality measuring instrument
