Zusammenfassung:Provided is an electrode slurry carbon nanotube liquid dispersion which improves charge/discharge cycle characteristics. An electrode slurry carbon nanotube liquid dispersion which is one aspect of the present disclosure and contains 0.1-1.5 mass% of carbon nanotubes, a dispersion medium, and carboxymethyl cellulose, the viscosity of which at 100s-1 in a 3% aqueous solution is 2-200mPa·s, wherein: the carboxymethyl cellulose content constitutes 50-250 parts by mass relative to 100 parts by mass of carbon nanotubes; the viscosity at 100s-1 is 50-200mPa·s in a state in which the carbon nanotubes are dispersed; and the particle distribution according to the laser diffraction method exhibits a D10 of 0.3-1.0µm, a D50 of 3-10µm and a D90 of 60µm or less in a state in which the carbon nanotubes are dispersed.
