Conductive Material Dispersed Solution, Cathode Slurry Composition and Cathode for Secondary Battery

Abstract

A conductive material dispersed solution includes an acrylic dispersant containing an acrylic compound, a conductive material, and a dispersion medium. A solids content of the conductive material dispersed solution is 3% by weight or more, and a shear viscosity value of the conductive material dispersed solution measured at 25° C. and a shear rate of 1/s is 70 Pa·s or less. Provided is a conductive material dispersed solution, in which the conductive material is pre-dispersed to an excellent level through an acrylic dispersant to effectively improve dispersibility of the conductive material when added to the cathode slurry composition, and high solids characteristics of the cathode slurry and the like may be secured by suppressing aggregation between active material particles in the cathode slurry.
