SULFUR-CARBON COMPOSITE, AND CATHODE AND LITHIUM SECONDARY BATTERY EACH COMPRISING SAME

The present invention relates to a sulfur-carbon composite and a cathode for a lithium secondary battery and a lithium secondary battery each comprising same. More specifically, carbons contained in the sulfur-carbon composite may include various shapes of carbons. Particularly, when applied as a cathode active material in a lithium battery, the sulfur-carbon composite containing a predetermined amount of planar-shaped carbons can prevent the elution of sulfur and improve the reaction rate in the cathode, thereby enhancing the performance of the lithium secondary battery.
