NOVELTY - Preparing graphene electrode involves dissolving the polyvinylidene fluoride (PVDF) in the nitrogen methyl pyrrolidone (NMP) while stirring under vacuum, adding conductive agent KS-6 and Super P to obtain slurry and stirring uniformly. The anode material is added to the obtained product and stirred continuously under vacuum, where anode material is nickel cobalt manganese ternary material. The obtained product is stirred uniformly, dried by belt coater for coating, coated on the aluminum foil and sprayed with graphen on the dry end position. USE - Method for preparing graphene electrode for scanning electron microscope analysis and rate performance (claimed). ADVANTAGE - The method enables to prepare graphene electrode in simple manner, is suitable for large scale production, has improved sheet graphene coating and reduced current charge battery temperature rise effect. DETAILED DESCRIPTION - Preparing graphene electrode involves dissolving the polyvinylidene fluoride (PVDF) in the nitrogen methyl pyrrolidone (NMP) while stirring under vacuum, adding conductive agent KS-6 and Super P to obtain slurry and stirring uniformly. The anode material is added to the obtained product and stirred continuously under vacuum, where anode material is nickel cobalt manganese ternary material. The obtained product is stirred uniformly, dried by belt coater for coating, coated on the aluminum foil and sprayed with graphen on the dry end position, where thickness of the graphene coating is 0.2-5 mu m. The drying is performed for the second time to obtain the positive pole piece and adopted roller machine for compacting under specific pressure of 1-1.5 megaPascal to obtain graphene electrode. The mass ratio of conductive agent, NMP, anode material and PVDF is 91-93:1.5-2.5:2-4.5:95-105.
