▎ 摘　　要

NOVELTY - Graphene dispersion comprises graphene and solvent, where the average thickness of graphene is 0.3-10 nm, the solubility parameter delta of solvent is 18-28 MPa(0.5), and the viscosity at a shear rate of 10/second and temperature of 25 degrees C is less than or equal to 10000 mPa.second when adjusted to 3 wt.% graphene concentration. USE - The graphene dispersion is useful in a positive electrode paste (claimed), and in conductive inks, wiring materials, antistatic films, heat conductive films, barrier films and conductive additive for lithium-ion batteries, which are used for portable devices, electric vehicles, household power storage, and for preparing a coating film. ADVANTAGE - The graphene dispersion has excellent fluidity and dispersibility, and the positive electrode paste improves the uniformity of coating film and the life of battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a positive electrode paste comprising positive electrode active material and the above-mentioned graphene dispersion.
