▎ 摘  要

NOVELTY - The graphene dispersion has a graphen. An amine compound has a molecular weight of 150 or less and an organic solvent. The mass ratio of the amine compound to the graphene is 0.005 or more and 0.30 or less. The amine compound is a compound having an alcoholic hydroxy group. The amine compound is a compound selected from the group consisting of ethanolamine, Propanolamine, isopropanolamine, Butanolamine, isobutanolamine and diglycolamine. The organic solvent is an organic solvent containing 50 by mass or more of N-methylpyrrolidone. USE - Graphene dispersion. ADVANTAGE - The viscosity range is preferred for ensuring that the graphene forms a favorable dispersion and the dispersion has a viscosity which allows the dispersion to be handled. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing an electrode paste.
