Abstract
The present invention provides a conductive material dispersed liquid, including: a conductive material which includes bundle-type carbon nanotubes; a dispersant; a dispersion medium, where a phase angle is in a range of 3° to 18° when measured by a rheometer at a frequency of 1 Hz; and a lithium secondary battery manufactured using the conductive material dispersed liquid. The conductive material dispersed liquid has high solid-like properties, and thus allows the formation of an electrode active material layer having a uniform thickness with no concern for collapse or occurrence of cracks during manufacture of an electrode, and thereby can improve the performance characteristics, particularly capacity characteristics, of a battery.
