More Information
Summary:The present invention relates to a dry manufacturing method of an electrode, which enables manufacture of a dry electrode having excellent mechanical and electrochemical properties. The dry manufacturing method of an electrode can include the steps of: primarily mixing a first carbon-based conductive material and an organic binder under application of shear force; secondarily mixing electrode active material particles with the primary mixture under application of rotational force of 500 to 2000 rpm; and calendering the secondary mixture to form an electrode film. 본 발명은 우수한 기계적 특성 및 전기화학적 특성을 갖는 건식 전극의 제조를 가능케 하는 전극의 건식 제조 방법에 관한 것이다. 이러한 전극의 건식 제조 방법은 제 1 탄소계 도전재 및 유기 바인더를 전단력의 인가 하에 1차 혼합하는 단계; 500 내지 2000 rpm의 회전력의 인가 하에, 상기 1차 혼합물에 전극 활물질 입자를 2차 혼합하는 단계; 및 상기 2차 혼합물을 캘린더링하여 전극 필름을 형성하는 단계를 포함할 수 있다.
