Title:
CATHODE ACTIVE MATERIAL FOR LITHIUM-SULFUR BATTERY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/212161
Kind Code:
A1
Abstract:
The present invention relates to a cathode active material for a lithium-sulfur battery, the cathode active material comprising: a sulfur-carbon composite; and a coating layer disposed on the surface of the sulfur-carbon composite and containing a carbon material. In addition, the present invention relates to a method for manufacturing a cathode active material for a lithium-sulfur battery, the method comprising a step of dispersing at least one of a carbon material and a sulfur-carbon compound in a dispersing medium and then wet mixing the dispersion to form a coating layer containing the carbon material on the surface of the sulfur-carbon composite.
