Title (EN) METHOD FOR PREDICTING PROCESSABILITY OF ELECTRODE SLURRY AND SELECTING ELECTRODE BINDER
(FR) PROCÉDÉ POUR PRÉDIRE L'APTITUDE AU TRAITEMENT D'UNE SUSPENSION D'ÉLECTRODE ET SÉLECTIONNER UN LIANT D'ÉLECTRODE
(KO) 전극 슬러리의 공정성 예측 및 전극 바인더 선정 방법
Abstract:
(EN) The present invention can predict the phase stability of electrode slurry by a simple method of checking a slurry viscosity change. Accordingly, prior to introduction into an electrode production process, only the electrode slurry that has high phase stability can be selected and introduced into the process, thereby increasing the process efficiency.
(FR) La présente invention permet de prédire la stabilité de phase d'une suspension d'électrode par un procédé simple de vérification d'un changement de viscosité de la suspension. Ainsi, avant l'introduction dans un processus de production d'électrode, seule une suspension d'électrode ayant une stabilité de phase élevée peut être sélectionnée et introduite dans le processus, ce qui permet d'augmenter l'efficacité du processus.
(KO) 본 발명은 슬러리의 점도 변화를 확인하는 간이한 방법으로 전극 슬러리의 상안정성을 예측할 수 있다. 따라서 전극 제조 공정에 투입 전 상안정성이 높은 전극 슬러리만을 선별하여 공정에 투입할 수 있으므로 공정 효율성이 증대되는 효과가 있다.
