EDLC Electrode active material for electric double layer capacitor
The present invention relates to a method for manufacturing an electrode active material for an EDLC, capable of preventing the degradation of an equivalent series resistance (ESR) characteristic by uniformly applying conductive additive powder when the conductive additive powder and activated carbon powder are applied on the surface of a current collector by granulating the activated carbon powder and the conductive additive powder. The method for manufacturing an electrode active material for an EDLC includes the steps of: preparing the activated carbon powder; preparing the conductive additive powder; mixing 87 to 96 wt% of the activated carbon powder with 4 to 13 wt% of the conductive additive powder using a nanoset mill or a ball mill; and manufacturing granular electrode powder by drying the mixture of the activated carbon powder and the conductive additive powder using a spray drying method if the activated carbon powder is mixed with the conductive additive powder.
본 발명은 활성탄 분말과 도전성 첨가제 분말을 과립형으로 제조함으로써 집전체의 표면에 활성탄 분말과 도전성 첨가제 분말을 도포 시 도전성 첨가제 분말이 균일하게 도포되어 ESR(equivalent series resistance) 특성이 저하되는 것을 방지할 수 있는 EDLC용 전극 활물질 제조방법에 관한 것으로, 활성탄 분말을 준비하는 단계; 도전성 첨가제 분말을 준비하는 단계; 활성탄 분말 87 내지 96wt％와 도전성 첨가제 분말 4 내지 13wt％를 나노셋 밀(nanoset mill)이나 볼밀(ball mill)을 이용하여 혼합하는 단계; 및 활성탄 분말과 도전성 첨가제 분말이 혼합되면 스프레이 건조방법을 이용해 건조시켜 과립형 전극분말을 제조하는 단계를 포함하는 것을 특징으로 한다.
