The present invention relates to a method for preparing aligned activated carbon nanofibers using an electrospinning method, and the preparation method presents a novel method. The preparation method can prepare the aligned activated carbon nanofibers having improved electrical characteristics by adjusting the degree of alignment according to the driving speed of a rotating current collector, and especially, when the rotating current collector is driven in one direction, providing an excellent path for increasing the ion transport speed. When the activated carbon nanofibers prepared by the preparation method are used as an electrode for a super capacitor, excellent electrochemical characteristics can be exhibited at the time of rapid charging and discharging. 본 발명은 전기방사법을 이용한 정렬된 활성탄소나노섬유 제조방법에 관한 것으로서, 상기 제조방법은 새로운 방법을 제시한다. 상기 제조방법은 회전 집전체 가동 속도에 따라 정렬도를 조절할 수 있으며, 특히 높은 속도로 회전 집전체를 가동할 경우 한방향으로 정렬됨으로써 이온 수송 속도를 높이기 위한 우수한 경로를 제공할 수 있어 전기적 특성이 향상된 활성탄소나노섬유를 제조할 수 있다. 상기 제조방법에 의해 제조된 활성탄소나노섬유를 슈퍼커피시터용 전극으로 이용할 경우 빠른 충방전 시 우수한 전기화학적 특성을 나타낼 수 있다.
