▎ 摘　　要

NOVELTY - Graphene composite conductive slurry comprises 3-8 wt.% graphene/carbon nanotubes mixture, 0.5-2 wt.% dispersant and 90-96.5 wt.% solvent. USE - The conductive slurry is used as conductive agent for positive electrode and negative electrode materials. ADVANTAGE - The conductive slurry has high performance, excellent stability, uniform dispersion and excellent electrochemical performance, exhibits synergistic effect, and is not easy to stack graphene and agglomerate and entangle carbon nanotubes, prepared by simple method, economical and suitable for large-scale industrial production and application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the conductive slurry, comprising dispersing graphene composite conductive slurry using combined method of grinding dispersion and ultrasonic dispersion.
