Beschreibung
Zusammenfassung:	The present invention provides a binder composition for a secondary battery electrode, a positive electrode for a lithium-sulfur secondary battery, and a lithium-sulfur secondary battery, comprising a lithium-substituted polyacrylic acid, a lithium-substituted carboxymethylcellulose, and a colloidal particulate water-based binder resin, thereby maintaining productivity and output performance at a high level, and improving an adhesion to the electrode. La présente invention concerne une composition de liant pour une électrode de batterie rechargeable, une électrode positive pour une batterie rechargeable au lithium-soufre, et une batterie rechargeable au lithium-soufre, comprenant un acide polyacrylique substitué au lithium, une carboxyméthylcellulose substituée au lithium, et une résine liante à base d'eau particulaire colloïdale, ce qui permet de maintenir la productivité et la performance de sortie à un niveau élevé, et d'améliorer une adhérence à l'électrode. 본 발명은 리튬 치환된 폴리아크릴산, 리튬 치환된 카르복시메틸셀룰로오스 및 콜로이드 입자형 수계 바인더 수지를 포함함으로써, 생산성 및 출력 성능을 높은 수준으로 유지하며, 전극에서의 접착력을 개선할 수 있는 이차전지 전극용 바인더 조성물, 리튬-황 이차전지용 양극 및 리튬-황 이차전지를 제공한다.
