Title:
CATHODE SLURRY COMPOSITION, CATHODE MANUFACTURED USING SAME, AND BATTERY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2019/139397
Kind Code:
A1
Abstract:
The present invention provides: a cathode slurry composition comprising a cathode active material, a binder, alcohol, and water, wherein the content of the alcohol is 0.1 to 10 wt%, based on the total weight of the composition; an electrode manufactured using same; and a battery including the electrode. The slurry composition for manufacture of a cathode according to the present invention has advantages in that: the dispersibility of a cathode active material and a conductive material is greatly improved; the surface roughness of an electrode is reduced; and the curling tendency of the electrode is significantly reduced. In addition, the slurry composition has an economic advantage in that there is no need to use a dispersant or the usage thereof can be significantly reduced.
