Abstract

The present invention provides a conductive material dispersed liquid including a conductive material which includes bundle-type carbon nanotubes; a dispersant which includes a hydrogenated nitrile-based rubber; and a dispersion medium, where a complex modulus (|G*| @ 1 Hz) is in a range of 20 to 500 Pa when measured by a rheometer at a frequency of 1 Hz, and a secondary battery manufactured using the same. The conductive material dispersed liquid has a controlled complex modulus to exhibit excellent dispersibility and powder resistance characteristics, and as a result, can greatly improve the output characteristics of batteries.
