Abstract
Official abstract text for this publication.
The present application relates to a cathode for a lithium-sulfur battery and a method of preparing the same. More specifically, the cathode for a lithium-sulfur battery according to an exemplary embodiment of the present application includes: a cathode active part including a sulfur-carbon composite; and a cathode coating layer including an amphiphilic polymer provided on at least one portion of a surface of the cathode active part and including a hydrophilic portion and a hydrophobic portion.
First claim
Opening claim text (preview).
1 . A method of preparing a cathode for a lithium-sulfur battery, the method comprising: forming a cathode active part comprising a sulfur-carbon composite; and forming a cathode coating layer, which comprises an amphiphilic polymer comprising a hydrophilic portion and a hydrophobic portion, on at least one portion of a surface of the cathode active part. 2 . The method of claim 1 , wherein the forming of the cathode coating layer utilizes a composition comprising the amphiphilic polymer, and utilizes dip coating, die coating, comma coating, gravure coating or bar coating methods. 3 . The method of claim 2 , wherein the composition comprising the amphiphilic polymer additionally comprises a solvent, and a content of the amphiphilic polymer is 1 to 30 wt % based on a total weight of the composition.
