CARBON MATERIAL DISPERSION AND USE THEREOF

WIPO Patent Application WO/2024/024162

A1

Provided is a carbon material dispersion capable of forming a coating film that has improved conductivity compared to when a single carbon material is used. The carbon material dispersion contains: at least two types of carbon materials selected from the group consisting of single-walled carbon nanotubes, multi-walled carbon nanotubes, and carbon black; an aqueous medium; a dispersant; and a binder resin, wherein when the carbon materials are a combination of single-walled carbon nanotubes and carbon black, the amount of carbon black is 0.001-0.43 parts by mass per 1 part by mass of the single-walled carbon nanotubes, and when the carbon materials are a combination of single-walled carbon nanotubes, multi-walled carbon nanotubes, and carbon black, the amount of carbon black is 0.001-0.43 parts by mass per 1 part by mass in total of the single-walled carbon nanotubes and the multi-walled carbon nanotubes.
