Abstract
Provided is a conductive material dispersion liquid for an electrochemical device capable of forming an electrode that has excellent flexibility and smoothness and can cause an electrochemical device to display excellent cycle characteristics. The conductive material dispersion liquid contains a conductive material, a dispersant including CNTs, and a dispersion medium. The conductive material dispersion liquid has a Casson viscosity of 30 (Pa·s)or less, Casson yield value of 20 Paor less, and hysteresis constant calculated by formula (I) (hysteresis constant C=(N−N)/N) of 0.7 or less. Nis viscosity (Pa·s) of the conductive material dispersion liquid at a shear rate of 10 swhen viscosity (25° C.) is measured while increasing shear rate from 10sto 10s, and Nis viscosity (Pa·s) thereof at a shear rate of 10 swhen viscosity (25° C.) is measured while decreasing shear rate from 10sto 10s.
