Beschreibung
Zusammenfassung:	The present invention relates to a sulfur-carbon composite for use in a positive electrode of a lithium-sulfur battery and to a method for manufacturing same, wherein the carbon composite comprises: a porous carbon substrate; and a sulfur-containing compound that fills in at least one of the outer surface and the inner pore surface of the porous carbon substrate, and all or part of the surface is covered with amphiphilic polythiophene. La présente invention concerne un composite soufre-carbone destiné à être utilisé dans une électrode positive d'une batterie lithium-soufre et son procédé de fabrication, le composite de carbone comprenant : un substrat de carbone poreux ; et un composé contenant du soufre qui remplit la surface externe et/ou la surface de pore interne du substrat de carbone poreux, la totalité ou une partie de la surface étant recouverte de polythiophène amphiphile. 본 발명은 리튬황 전지의 양극에 사용하기 위한 황-탄소 복합체 및 이의 제조방법에 관한 것으로서, 상기 탄소 복합체는 다공성 탄소 기재; 및 상기 다공성 탄소 기재의 외부 표면 및 기공 내부 표면 중 어느 하나 이상에 충진된 황 함유 화합물;을 포함하고, 양친성 폴리티오펜에 의해 표면의 전부 또는 일부가 피복된 것으로 한다.
