Abstract
(EN) According to an evaluation system and method for dissolution quality of a binder solution for a secondary battery electrode of the present invention, an electrode slurry is prepared from a binder solution having a predetermined amount or greater of cumulative filtration or a predetermined value or less of flow decline rate, whereby an electrode for a secondary battery can be improved in quality.
(FR) La présente invention concerne un système et un procédé d'évaluation de la qualité de dissolution d'une solution de liant destinée à une électrode d'une batterie secondaire. Selon l'invention, une suspension d'électrode est préparée à partir d'une solution de liant présentant une quantité de filtration cumulative égale ou supérieure à une quantité prédéfinie ou une valeur de taux de baisse d'écoulement égale ou inférieure à une valeur prédéfinie, ce qui permet d'améliorer la qualité d'une électrode destinée à une batterie secondaire.
(KO) 본 발명의 이차전지 전극용 바인더 용액의 용해 품질 평가시스템 및 평가방법에 따르면, 소정량 이상의 여과누적량 또는 소정값 이하의 유량저하율을 가지는 바인더 용액으로 전극 슬러리를 제조함으로써, 이차전지용 전극의 품질을 개선할 수 있다.
