Title:
CARBON NANOTUBE DISPERSED LIQUID, ELECTRODE COATING MATERIAL USING SAME, ELECTRODE AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/070397
Kind Code:
A1
Abstract:
The present invention provides a carbon nanotube dispersed liquid which exhibits excellent dispersion stability of single-walled carbon nanotubes. A carbon nanotube dispersed liquid according to one embodiment of the present invention contains single-walled carbon nanotubes, carboxymethyl cellulose and/or a salt thereof, and water; and the content of the single-walled carbon nanotubes is 0.47 to 1.00% by mass. The carboxymethyl cellulose and/or a salt thereof contains at least one kind that has a degree of etherification of 0.65 to 0.85 and a weight average molecular weight of 120,000 to 250,000. The content of the carboxymethyl cellulose and/or a salt thereof is 120 to 220 parts by mass relative to 100 parts by mass of the single-walled carbon nanotubes.
