Electrode slurry carbon nanotube liquid dispersion, negative electrode slurry, non-aqueous electrolyte secondary battery, and method for producing electrode slurry carbon nanotube liquid dispersion

A dispersion of carbon nanotubes for an electrode slurry, including:

• greater than or equal to 0.1 mass % and less than or equal to 1.5 mass % of carbon nanotubes;
• a dispersion medium;
• and
• a carboxymethylcellulose in which a 3% aqueous solution thereof has a viscosity at 100 s−1 of greater than or equal to 2 mPa·s and less than or equal to 200 mPa·s, wherein
• a content of the carboxymethylcellulose is greater than or equal to 50 parts by mass and less than or equal to 250 parts by mass relative to 100 parts by mass of the carbon nanotubes,
• in a state of dispersing the carbon nanotubes, a viscosity at 100 s−1 is greater than or equal to 50 mPa·s and less than or equal to 200 mPa·s, and
• in a state of dispersing the carbon nanotubes, a particle size distribution by a laser diffraction method has a D10 of greater than or equal to 0.3 μm and less than or equal to 1.0 μm, a D50 of greater than or equal to 3 μm and less than or equal to 10 μm, and a D90 of less than or equal to 60 μm.
