Carbon nanotube dispersion composition, carbon nanotube resin composition, mixture slurry, electrode film, and non-aqueous electrolyte secondary battery

Abstract

Provided is a carbon nanotube dispersion composition including carbon nanotubes, a dispersant, and a solvent and satisfying (1) and (2) as follows: (1) an average outer diameter of the carbon nanotubes calculated from an SEM image obtained by observing the carbon nanotubes included in the carbon nanotube dispersion composition is 15 nm or more and 50 nm or less; and (2) when a target pixel group in the SEM image obtained by observing the carbon nanotubes included in the carbon nanotube dispersion composition is set as the carbon nanotubes, and a value obtained by dividing an absolute maximum length by a length of a free curve, that is, a skeleton length, is set as linearity, a proportion of carbon nanotubes with a linearity of 0.9 or more among carbon nanotubes with a skeleton length of 1 μm or more is 40% or more and 90% or less.
