NEGATIVE ELECTRODE FOR LITHIUM-SULFUR BATTERY AND LITHIUM-SULFUR BATTERY INCLUDING SAME

The present invention relates to a negative electrode for a lithium-sulfur battery and a lithium-sulfur battery comprising the same, more specifically to a negative electrode for a lithium-sulfur battery comprising a negative electrode current collector and a protective layer located on at least one surface of the negative electrode current collector and containing graphene. [0002] The negative electrode for the lithium-sulfur battery of the present invention improves the lifetime characteristics of the lithium-sulfur battery by preventing contact between lithium polysulfide and the negative electrode current collector.
