Abstract:
(EN) The present invention relates to an organic positive electrode active material for an aqueous redox flow battery and, more specifically, to a technique for remedying the disadvantages of a conventional aqueous redox flow battery by utilizing an organic positive electrode active material. The aqueous redox flow battery utilizing the positive electrode active material according to the present invention does not have the problem of metal precipitation and can be used at a high concentration due to an increase in solubility depending on the solvent, and thus, can not only achieve high energy density, but can also obtain a high operating voltage, and can increase energy efficiency. In addition, since an expensive organic electrolyte does not have to be used, economic feasibility is excellent.
(FR) La présente invention concerne un matériau actif d'électrode positive organique pour une batterie à flux redox aqueux et, plus spécifiquement, une technique pour remédier aux inconvénients d'une batterie à flux redox aqueux classique en utilisant un matériau actif d'électrode positive organique. La batterie à flux redox aqueux utilisant le matériau actif d'électrode positive selon la présente invention ne présente pas le problème de précipitation de métal et peut être utilisée à une concentration élevée grâce à une augmentation de solubilité dépendant du solvant, et, par conséquent, peut non seulement atteindre une densité d'énergie élevée, mais peut également obtenir une tension de fonctionnement élevée, et peut augmenter l'efficacité énergétique. En outre, étant donné qu'il n'est pas necessaire d'utiliser un électrolyte organique onéreux, la faisabilité économique est excellente.
(KO) 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.
