Carbon nanotube dispersion composition, composite material slurry, electrode film, and non-aqueous electrolyte secondary battery

Abstract

Provided are a carbon nanotube dispersion composition and a non-aqueous electrolyte secondary battery by using an electrode composite material slurry and an electrode film using the composition. The carbon nanotube dispersion composition contains containing carbon nanotubes having an average outer diameter of 3 nm or less, a polymer component, and a solvent, in which the polymer component contains a polyvinylidene fluoride resin, which may have a substituent as a main component, and the carbon nanotube dispersion composition has a particle diameter D90 at 90% volume accumulation in the particle size distribution measured by laser diffraction method of 2.0 μm or more and less than 20.0 μm, and a pH of 7.5 or higher.
