Abstract
A positive electrode containing a sulfur-carbon composite and a lithium secondary battery including the same are discussed. More specifically, a network-shaped coating layer including a conductive polymer on a surface of the sulfur-carbon composite, and thus the conductivity of the sulfur-carbon composite is enhanced and also, lithium ions move freely, and accordingly, when applied to lithium secondary batteries, the sulfur-carbon composite can enhance the performance of batteries.
