Abstract: front page image
(EN)The present invention relates to a polymer-sulfur copolymer, a method for preparing the same, and a lithium-sulfur battery comprising the same. As a result of a carrier being polymerized in the polymer-sulfur copolymer according to the present invention there is no concern about the elution of the carrier, and because sulfur is covalently bonded to a polymer and uniformly distributed within the copolymer, the polysulfide elution problem when the polymer-sulfur copolymer is used as a cathode active material of a lithium-sulfur battery can be improved upon. Also, it is possible to realize a high capacity battery as the polymer-sulfur copolymer has a high amount of sulfur impregnation.
(FR)La présente invention concerne un copolymère polymère-soufre, son procédé de préparation et une batterie lithium-soufre le comprenant. Étant donné qu'un vecteur est polymérisé dans le copolymère polymère-soufre selon la présente invention, il n'y a pas de risque d'élution du vecteur, et étant donné que le soufre est lié par liaison covalente à un polymère et uniformément réparti dans le copolymère, le problème d'élution d'un polysulfure peut être résolu quand le copolymère polymère-soufre est utilisé comme matériau actif de cathode d'une batterie lithium-soufre. En outre, il est possible de réaliser une batterie de grande capacité étant donné que le copolymère polymère-soufre présente une grande quantité d'imprégnation de soufre.
(KO)본 발명은 고분자-황 공중합체, 이의 제조방법 및 이를 포함하는 리튬-황 전지에 관한 것이다. 본 발명에 따른 고분자-황 공중합체는 담체가 고분자화 되어 있어 담체 용출 우려가 없고, 황이 고분자에 공유결합되어 공중합체 내에 일정한 크기로 고르게 분포되어 있으므로 리튬-황 전지의 양극 활물질로 사용시 폴리설파이드의 용출문제를 개선할 수 있다. 또한 높은 황 함침량을 가지므로 고용량 전지의 구현이 가능하다.
