Zusammenfassung:본 발명은 비수계 용매 치환된 수계 바인더, 및 비수계 바인더가 블렌딩된 절연 조성물에 관한 것으로, 상기 절연 조성물은, 전극 절연층으로 적용시, 습윤 접착력이 우수하면서도 활물질 슬러리와의 겔화 발생을 방지할 수 있으며, 활물질 슬러리와 절연 조성물을 동시 코팅하는 공정에 효과적으로 적용 가능하다. Disclosed herein relates to an insulation composition blended with a non-aqueous solvent-dispersed aqueous binder and a non-aqueous binder, wherein the insulation composition can prevent gelation with an active material slurry while having excellent wet adhesion when applied as an electrode insulating layer, and is effectively applicable to a process of co-coating an active material slurry and an insulation composition.
