Abstract: front page image
(EN)The present invention relates to a sulfur-carbon composite and a lithium-sulfur battery comprising the same and, more particularly, to a sulfur-carbon composite and a lithium-sulfur battery comprising the same, the composite comprising: a porous carbon material; and sulfur at at least a part of the surface and the inside of the porous carbon material, wherein the porous carbon material includes ion conductive polymer-containing coating layers on the inner and the outer surface thereof. The present invention includes the ion conductive polymer coating layers on the surfaces of the porous carbon material to improve the conduction of lithium ion to the cathode, thereby enhancing the capacity and lifespan characteristics of the lithium-sulfur battery.
(FR)La présente invention concerne un composite de soufre-carbone et une batterie au lithium-soufre le comprenant. Le composite comprend: un matériau carboné poreux; et du soufre sur au moins une partie de la surface et à l'intérieur du matériau carboné poreux, le matériau carboné poreux comprenant des couches de revêtement contenant un polymère conducteur d'ions à l'intérieur et sur sa surface externe. La présente invention comprend les couches de revêtement de polymère conducteur d'ions sur les surfaces du matériau carboné poreux pour améliorer la conduction des ions de lithium vers la cathode, ce qui permet d'améliorer les caractéristiques de capacité et de durée de vie de la batterie au lithium-soufre.
(KO)본 발명은 황-탄소 복합체 및 이를 포함하는 리튬-황 전지에 관한 것으로, 더욱 구체적으로 다공성 탄소재; 및 상기 다공성 탄소재의 내부 및 표면 중 적어도 일부에 황을 포함하는 황-탄소 복합체의 상기 다공성 탄소재의 내부 및 외부 표면은 이온 전도성 고분자를 포함하는 코팅층을 포함하는 황-탄소 복합체 및 이를 포함하는 리튬-황 전지에 관한 것이다. 본 발명은 다공성 탄소재 표면에 다공성 탄소재 표면에 이온 전도성 고분자 코팅층을 포함하여 양극으로의 리튬 이온 전도 특성이 개선되며 리튬-황 전지의 용량 및 수명 특성을 향상시킬 수 있다.
