Carbon nanotube dispersion liquid for non-aqueous electrolyte secondary battery and resin composition using it, mixture slurry, electrode film, non-aqueous electrolyte secondary battery.

摘要

PROBLEM TO BE SOLVED: To provide a carbon nanotube dispersion liquid, a carbon nanotube resin composition and a mixed material slurry having high dispersibility in order to obtain an electrode film having high adhesion and conductivity. More specifically, a non-aqueous electrolyte secondary battery having excellent rate characteristics and cycle characteristics is provided. A carbon nanotube dispersion liquid containing carbon nanotubes, a dispersant, and a solvent is provided as described below. A carbon nanotube dispersion liquid for a non-aqueous electrolyte secondary battery, which satisfies 1) to (3). (1) The average outer diameter of the carbon nanotubes is more than 3 nm and 25 nm or less, (2) the BET specific surface area of the carbon nanotubes is 150 to 800 m2 / g, and (3) the average fiber length of the carbon nanotubes in the carbon nanotube dispersion liquid. However, it is 0.8 to 3.5 μm. [Selection diagram] None
