▎ 摘  要

NOVELTY - Preparing graphene lithium ion battery conductive agent involves preparing graphene material by mechanical peeling method, adding 0.5-5 pts. wt. binder to 87-98.2 pts. wt. solvent, stirring and mixing in a high-speed mechanical mixer for 0.5-2 hours to fully mixed to obtain binder / solvent mixed solution, adding 1-5 pts. wt. graphene material prepared to the binder / solvent mixture and continue to stirring and mixing for 1-2 hours to obtain graphene slurry material, adding 0.3-3 pts. wt. other conductive components to the graphene slurry, stirring and mixing for 0.5-1 hours, and then transferring the slurry to a homogeneous emulsifier for dispersion for 3-6 hours to obtain final product. USE - -Method for preparing graphene lithium ion battery conductive agent. ADVANTAGE - The method enables to prepare graphene lithium ion battery conductive agent has high capacity, high coulombic efficiency, and good circulation stability.
