▎ 摘　　要

NOVELTY - Aqueous-organic redox flow battery, comprises electrodes, membrane, electrolytes, pumps for delivering electrolytes, pipelines and stack control management systems. The electrolyte comprises cathode active material and anode active material. The cathode active material is a bipyridine-quaternary ammonium salt derivative (I)-(III). The anode active material is a Tempo-quaternary ammonium salt derivative (IV)-(VI). USE - Used as aqueous-organic redox flow battery. ADVANTAGE - The aqueous-organic redox flow battery: has higher water solubility of the active material and more stable battery performance when compared with the existing Tempo/MV organic flow battery, effectively expands the structural types of Tempo and bipyridyl derivatives, reduces the requirements for the membrane of the flow battery and provides more choices for the organic active materials of the flow battery.
