Abstract
The present invention relates to a method for manufacturing a carbon-sulfur composite, a carbon-sulfur composite manufactured by the method, and a lithium-sulfur battery including the same. In the carbon-sulfur composite manufactured by the method for manufacturing the carbon-sulfur composite, the sulfur is filled up to inside of the carbon balls, and thereby uniformly distributed. Accordingly, the sulfur content is increased, resulting to increase of capacity property, and also electrode structure does not collapse even though the sulfur is changed to a liquid phase while charging or discharging the battery, resulting to showing stable cycle property.
