Zusammenfassung: | A lithium-sulfur battery according to the present invention can be structured such that a jelly roll-shaped electrode assembly constituting the battery is covered with a polymer film having heat-shrinking properties, and the electrode assembly is pressed in the direction from the outside to the inside by shrinking the polymer film during activation. Therefore, the battery is driven while the electrode assembly is appropriately pressed, such that electrochemical performance can be maximized.
Une batterie au lithium-soufre selon la présente invention peut être structurée de telle sorte qu'un ensemble électrode en forme de rouleau de gelée constituant la batterie est recouvert d'un film polymère ayant des propriétés de thermorétraction, et l'ensemble électrode est pressé dans la direction de l'extérieur vers l'intérieur par rétraction du film polymère pendant l'activation. Par conséquent, la batterie est excitée lorsque l'ensemble électrode est pressé de manière appropriée, de telle sorte que les performances électrochimiques peuvent être maximisées.
본 발명에 따른 리튬황 전지는 이를 구성하는 젤리롤 형태의 전극 조립체가 열수축 특성을 갖는 고분자 필름에 의해 피복되고, 활성화 공정 시 고분자 필름을 수축시킴으로써 외부에서 내부 방향으로 전극 조립체가 가압된 구조를 가질 수 있다. 이에 전극 조립체가 적절히 가압된 상태에서 전지가 구동되므로 전기화학적 성능 발현을 최대화할 수 있다. |
