▎ 摘  要

NOVELTY - Preparing graphene conductive slurry, comprises (i) mixing dispersant with water and first pre-dispersing to obtain dispersion liquid, (ii) mixing dispersion liquid with graphene, second pre-dispersing, and performing first high-energy dissociation to obtain suspension, (iii) mixing suspension with thickening agent, stirring, and performing second high-energy dissociation, and shearing to obtain graphene conductive slurry. USE - The graphene conductive slurry is useful in preparing lithium ion battery electrodes (claimed). ADVANTAGE - The method: utilizes water as solvent; and utilizes pre-dispersion device and high-energy dissociation device to perform radial size treatment and lamellar peeling of the graphene. The graphene conductive slurry has excellent electrical conductivity and viscosity properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene conductive slurry prepared by above method.
