NOVELTY - A conductive slurry preparing method involves drying carbon nanotubes to obtain dry carbon nanotubes. The dried carbon nanotubes are pre-mixed with a dispersant and a binder under a nitrogen atmosphere to obtain a premix. The premix is coarsely grinded to obtain a coarse grinding material followed by grinding the coarse grinding material to obtain a fine grinding material, drying three-dimensional graphene to obtain dry graphene, mixing fine grinding material with dried graphene and finely grinding to obtain a conductive slurry, and returning part of conductive paste to the fine grinding. USE - Method for preparing conductive slurry. ADVANTAGE - The conductive slurry has high conductivity and long stable period.
