Title (EN) CATHODE ACTIVE MATERIAL COMPRISING POLYIMIDE, MANUFACTURING METHOD THEREOF, AND LITHIUM-SULFUR BATTERY COMPRISING SAME
(FR) MATIÈRE ACTIVE DE CATHODE COMPRENANT DU POLYIMIDE, SON PROCÉDÉ DE FABRICATION, ET BATTERIE AU LITHIUM-SOUFRE LA COMPRENANT
(KO) 폴리이미드를 포함하는 양극 활물질, 이의 제조방법 및 이를 포함하는 리튬-황 전지
Abstract: front page image
(EN)The present invention relates to a cathode active material for a lithium-sulfur battery comprising polyimide and, more particularly, to a cathode active material having a composite of polyimide and carbon-based secondary particles complexed with sulfur particles, a method for manufacturing the same, and a lithium-sulfur battery comprising the same. When the complexed cathode active material comprising polyimide according to the present invention is applied to a lithium-sulfur battery, elution of polysulfide is suppressed, such that lifetime characteristics and energy efficiency are improved.
(FR)La présente invention concerne une matière active de cathode pour une batterie au lithium-soufre comprenant du polyimide et, plus particulièrement, une matière active de cathode ayant un composite de polyimide et des particules secondaires à base de carbone complexées avec des particules de soufre, son procédé de fabrication, et une batterie au lithium-soufre la comprenant. Lorsque la matière active de cathode complexée comprenant du polyimide selon la présente invention est appliquée à une batterie au lithium-soufre, l'élution du polysulfure est supprimée, de telle sorte que les caractéristiques de durée de vie et l'efficacité énergétique sont améliorées.
(KO)본 발명은 폴리이미드를 포함하는 리튬-황 전지용 양극 활물질에 관한 것으로, 보다 상세하게는 폴리이미드와 탄소계 2차 입자의 복합체를 황 입자와 복합화한 양극 활물질, 이의 제조방법 및 이를 포함하는 리튬-황 전지에 관한 것이다. 본 발명에 따른 폴리이미드를 포함하여 복합화된 양극 활물질을 리튬-황 전지에 적용하면, 폴리설파이드의 용출을 억제하여, 수명특성과 에너지 효율이 향상된다.
