Beschreibung
Zusammenfassung:	The present invention relates to a negative electrode slurry composition comprising a carbon nanotube dispersion, a negative electrode active material, and a binder, wherein the negative electrode active material comprises a silicon-based negative electrode active material, and wherein the carbon nanotube dispersion includes carbon nanotubes (CNT) having a Brunauer-Emmett-Teller (BET) specific surface area of 800 m2/g or more, a dispersant, and a water-based solvent, wherein the dispersant includes a polymer dispersant containing an amine and a phenolic compound containing two or more aromatic rings.
