Zusammenfassung:Provided are a method for manufacturing a sulfur-carbon composite, a positive electrode for a lithium secondary battery comprising the sulfur-carbon composite manufactured by the method, and a lithium secondary battery comprising the positive electrode. The method for manufacturing a sulfur-carbon composite comprises the following steps: (a) mixing a carbon-based material with sulfur or a sulfur compound; (b) putting the sulfur-carbon mixture mixed in the step (a) and a liquid vaporizable in a step (c) into a sealed container; and (c) heating the sealed container to a temperature of 120-200°C. 본 발명은 (a) 탄소계 물질을 황 또는 황 화합물과 혼합하는 단계; (b) 상기 (a)단계에서 혼합된 황-탄소 혼합물과 하기 (c)단계에서 기화 가능한 액체를 밀봉 용기에 넣어주는 단계; 및 (c) 상기 밀봉 용기를 120 내지 200℃의 온도로 가열하는 단계;를 포함하는 황-탄소 복합체의 제조방법, 그 방법에 의해 제조된 황-탄소 복합체를 포함하는 리튬 이차 전지용 양극, 및 상기 양극을 포함하는 리튬 이차 전지를 제공한다.
