▎ 摘  要

NOVELTY - Positive electrode comprises a positive electrode current collector and a positive electrode active material layer positioned on at least one surface of the positive electrode current collector, where the positive electrode active material layer is a positive electrode active material and has a sulfur-carbon composite having a island-shaped carbon coating layers (13) on its surface. The carbon coating layer includes reduced graphene oxide. USE - The positive electrode is used in lithium-sulfur battery (claimed). ADVANTAGE - The positive electrode develops a lithium-sulfur battery capable of improving the electrochemical reactivity of the positive electrode through a simple process to realize excellent performance and driving stability, and maximizes the capacity expression of the positive electrode, and realizes a lithium-sulfur battery having high capacity and high energy density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of manufacturing the positive electrode for a lithium-sulfur battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the configuration of the positive electrode active material layer. 11Sulfur-carbon composite 13Island-shaped carbon coating layer 15Carbon bridge
