FIELD: electricity.
SUBSTANCE: cathode for the lithium-sulfur battery includes the active portion of the cathode, including the sulfur-carbon composite, and the cathode coating layer provided on at least a portion of the surface of the active cathode portion and comprising an inorganic oxide. The cathode coating layer comprises pores having an average diameter of 0.5 to 10 mcm, and the porosity of the cathode coating layer is 20 to 70%.
EFFECT: invention allows to improve the cyclic characteristics of the cathode.
