The present invention relates to an electrode slurry coating device for a secondary battery and an electrode slurry coating method. The electrode slurry coating device includes a slurry transport pipe having a double structure composed of first and second pipes, so that the temperature of electrode slurry can be maintained constant when the electrode slurry stored in a slurry tank is transported to a slot die. Accordingly, the electrode slurry can be uniformly applied to a current collector to reduce a defect rate in manufacturing an electrode. 본 발명은 이차전지용 전극 슬러리 코팅장치 및 전극 슬러리 코팅방법에 관한 것으로, 제1 및 제2 관으로 이루어진 이중 구조의 슬러리 이송배관을 포함하여, 슬러리 탱크에 저장된 전극 슬러리를 슬롯 다이로 이송시 전극 슬러리의 온도를 일정하게 유지할 수 있다. 이에 따라, 전극 슬러리를 집전체에 균일하게 도포시켜 전극 제조의 불량률을 감소시킬 수 있다.
