Title:
GRAPHENE/ORGANIC SOLVENT DISPERSION, PRODUCTION METHOD OF GRAPHENE-ACTIVE MATERIAL COMPOSITE PARTICLE, AND PRODUCTION METHOD OF ELECTRODE PASTE
Document Type and Number:
Japanese Patent JP2017218373
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide graphene which is highly dispersive, and which has a shape capable of maintaining high electric conductivity and high ion conductivity when used for a production raw material of an electrode material.SOLUTION: A graphene/organic solvent dispersion comprises graphene dispersed in an organic solvent, and a graphene film formed by applying and film-forming the graphene/organic solvent dispersion of which the solid fraction is adjusted to be 0.005 to 0.012, has surface roughness of 1.0 μm or less when measured by a laser microscope with a wavelength of 408 nm by using an objective lens with magnification of 50 and at measurement pitch of 0.100 μm.SELECTED DRAWING: None
