▎ 摘　　要

NOVELTY - Composite slurry com(comprises 2-3 wt.% modified carbon nanotubes, 1-2 wt.% graphene, 0.5-1.5 wt.% dispersant, and 93.5-96.5 wt.% solvent, the modified carbon nanotubes is modified carbon nanotubes with aniline groups introduced. The solvent is N-methylpyrrolidone. The dispersant includes polyvinylpyrrolidone, polyvinylidene fluoride, sodium dodecylbenzenesulfonate, sodium dodecyl sulfate and/or ethylene glycol amine. USE - The composite slurry is useful in anode material for lithium ion batteries (claimed). ADVANTAGE - The slurry: solves problem of metal ion dissolution of cathode ternary material caused by high working voltage and high working temperature of existing lithium ion cathode material; has low viscosity, good dispersibility, high utilization rate of conductive agent, which can alleviate dissolution of metal ions during charge and discharge process of the ternary anode; and is safe and environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing composite slurry.
