Conductive material dispersion liquid, electrode slurry comprising same, and lithium secondary battery comprising same

Abstract

A conductive material dispersion according to an embodiment of the present invention may comprise: a conductive material comprising carbon nanotubes; a hydrogenated nitrile-based copolymer; a polyamine compound; and a solvent, the conductive material dispersion may have an amine value of 5 to 30 mgKOH / g. An electrode paste according to an embodiment of the present invention may include a positive electrode active material and a conductive material dispersion. According to the invention, the dispersibility of the conductive material dispersion liquid and the electrode slurry can be improved.
