Carbon nanotube slurry and slurry for electrode

Abstract

Provided is a carbon nanotube dispersion liquid suitable for manufacturing an electrode for a high-performance lithium-ion secondary battery or the like. More specifically, provided is a carbon nanotube slurry containing at least carbon nanotubes, a dispersant, and a non-aqueous solvent. The carbon nanotubes have a BET specific surface area of 70 m2 / g to 180 m2 / g, and the peak intensity ratio G / D of the slurry, in Raman spectroscopy is 1.0 – 2.5. (In the Raman spectrum, the peak intensity ratio G / D represents a ratio where G is the maximum intensity of a G-band scattered light peak in the range of 1570 cm-1 to 1620 cm-1, and D is the maximum intensity of a D-band scattered light peak in the range of 1320 cm-1 to 1370 cm-1).
