Abstract

본 발명은 수계 레독스 플로우 전지용 유기계 양극 활물질에 관한 것으로, 보다 상세하게는 유기계 양극 활물질을 적용하여 종래의 수계 레독스 플로우 전지의 단점을 보완하는 기술에 관한 것이다. 본 발명에 따른 양극 활물질이 적용된 수계 레독스 플로우 전지는 금속 석출의 문제점이 없을 뿐만 아니라 용매에 따른 용해도 증가로 고농도 사용이 가능하여 고에너지 밀도를 달성할 수 있을 뿐만 아니라, 높은 작동전압을 얻을 수 있으며, 에너지 효율을 높일 수 있는 효과가 있다. 또한 고가의 유기 전해액을 적용하지 않아도 되므로 경제성이 우수하다.
