Abstract

본 발명은 양극활물질, 도전제, 탄소섬유 전구체를 포함하는 방사용액의 전기방사 방법에 의하여 제조된 탄소나노파이버, 및 결착제를 포함하는 전기저장장치의 양극 제조용 조성물, 상기 조성물로 제조되는 전기저장장치용 양극, 및 이를 포함하는 전기저장장치에 관한 것이다. 상기 전기저장장치의 양극 제조용 조성물은 기존의 도전제, 분산제 및/또는 결착제의 일부 또는 전부가 탄소나노파이버로 대체됨으로써, 양극의 비표면적 및 전기전도도를 획기적으로 향상(저항을 감소)시키며, 그에 따라 양극활물질의 효율 및 용량을 극대화시킨다.
