Zusammenfassung:	According to the present invention, a coating apparatus of an active material for a secondary battery is provided to coat an electrode base material of a secondary battery with an active material, and can reduce an area where an active material is not applied. The coating apparatus of an active material for a secondary battery comprises: a slurry storage tank to store slurry including an active material for a secondary battery; a slurry discharge part coating an electrode base material with the slurry transferred from the slurry storage tank; a coating roll which is installed to be separated at a predetermined interval from the slurry discharge part and transfers the electrode base material; a pump to transfer the slurry from the slurry storage tank to the slurry discharge part; a valve installed between the pump and the slurry discharge part to control the discharge of the slurry; and a valve control part to electrically control the valve. The slurry discharge part consists of multiple discharge nozzles. 본 발명의 이차전지용 활물질 코팅장치는, 이차전지의 전극 기재에 활물질을 코팅하기 위한 이차전지용 활물질 코팅장치로서, 이차전지용 활물질이 포함된 슬러리가 저장된 슬러리 저장탱크와, 상기 슬러리 저장탱크에서 이송된 슬러리를 전극 기재에 코팅하는 슬러리 토출부와, 상기 슬러리 토출부와 소정의 간격으로 이격되어 설치되고 상기 전극 기재를 이송시키는 코팅 롤과, 상기 슬러리 저장탱크로부터 슬러리 토출부로 슬러리를 이송시키기 위한 펌프와, 상기 펌프와 상기 슬러리 토출부 사이에 설치되어 슬러리의 토출을 조절하는 밸브와, 상기 밸브를 전기적으로 제어하기 위한 밸브 제어부을 포함하고, 상기 슬러리 토출부는 복수개의 토출 노즐로 이루어진 것을 특징으로 한다.
