Cathode slurry composition, cathode for secondary battery and lithium secondary battery

Abstract

A cathode slurry composition according to an aspect includes a cathode active material, an acrylic dispersant, and a solvent. The cathode slurry composition has a solids content of 65% by weight or more, and a shear viscosity value of 150 Pa·s or less measured at a temperature of 25° C. and a shear rate of 1/s. According to the aspect, a cathode slurry composition having excellent dispersibility, flowability, and the like, as aggregation between active cathode material particles is suppressed, and having a relatively high solids content and low shear viscosity may be provided. According to the cathode slurry composition, a cathode for a secondary battery may be formed having excellent processability without limitations on electrode loading design, coating speed setting, and the like.
