Title
(EN) METHOD FOR MANUFACTURING SEPARATOR FOR ELECTROCHEMICAL DEVICE
(FR) PROCÉDÉ DE FABRICATION DE SÉPARATEUR DESTINÉ À UN DISPOSITIF ÉLECTROCHIMIQUE
(KO) 전기화학소자용 세퍼레이터의 제조방법
Abstract
(EN)
One aspect of the present invention provides a separator and a manufacturing method therefor, the separator having a Lami strength equal to or similar to that of a conventional separator according to the use of a polyvinylpyrrolidone binder polymer in a predetermined amount, compared with a polyvinlylidenefluoride-based binder polymer and, simultaneously, having improved heat resistance and reduced resistance.
(FR)
Un aspect de la présente invention concerne un séparateur et son procédé de fabrication. Le séparateur possède une résistance Lami égale ou similaire à celle d'un séparateur classique selon l'utilisation d'un polymère liant de polyvinylpyrrolidone dans une quantité prédéterminée, par comparaison avec un polymère liant à base de fluorure de polyvinylidène et, simultanément, possède une résistance à la chaleur améliorée et une résistance réduite.
(KO)
본 발명의 일 측면은 폴리비닐피롤리돈 바인더 고분자를 폴리비닐리덴 플루오라이드계 바인더 고분자 대비 소정 함량으로 사용함에 따라 종래와 동등 또는 유사한 Lami Strength를 가지며 동시에 내열성이 향상되고, 저항이 낮은 세퍼레이터 및 이의 제조방법을 제공한다.
