Manufacturing method of carbon nanotube dispersion liquid, resin composition using the same, mixture slurry, electrode film, and nonaqueous electrolyte secondary battery

Abstract

A manufacturing method of a carbon nanotube dispersion liquid containing carbon nanotubes, a dispersant, and a solvent includes at least the following steps. A dispersion treatment is performed on the carbon nanotubes having a BET specific surface area (m2/g) of 220 to 800, 20 parts by mass to 100 parts by mass of the dispersant relative to 100 parts by mass of the carbon nanotube, and the solvent using a homogenizer or a paint conditioner. A fiber length of the carbon nanotubes in the carbon nanotube dispersion liquid obtained from the dispersion treatment ranges from 0.8 μm to 3.5 μm.
