NOVELTY - Preparing high performance composite conductive slurry, comprises (i) placing the graphite in the mixed solution composed of oxidant and intercalation agent, ultrasonically stirring at 25-80℃ and filtering, (ii) adding the graphene product, carbon nanotubes, conductive carbon black, persulfate and anionic surfactant into water, stirring until the mixture is uniform, and dispersing, (iii) adding the rare earth mixture to the primary mixed solution, ultrasonically dispersing for 0.3-0.8 hours, adding conductive adhesive and stirring, and (iv) placing the micron-sized high-purity silicon powder and the grinding ball in a grinding tank, and vacuumizing the system by vacuum pump, and introducing protective atmosphere. USE - Preparation method of high performance composite conductive slurry for lithium battery used in portable electronic device, electric automobile, power system-chemical power supply requirement and performance requirement of rapid growth. ADVANTAGE - The method provides high performance composite conductive slurry having excellent electrical performance and creep resistance.
