||PCT/KR2014/008245||UNIVERSITY-INDUSTRY FOUNDATION, YONSEI UNIVERSITY||SHUL, Yong Gun|
The present invention relates to an electrolyte composition containing an active material and an organic acid having one or more carboxylic acid groups, and a redox flow battery using the same. The electrolyte composition according to the present invention contains the organic acid having one or more carboxylic acid groups instead of an inorganic acid having high acidity such as a sulfuric acid and a hydrochloric acid, thereby ameliorating cell corrosion and improving the stability of the battery if an electrolyte leaks out. In addition, when applied to the redox flow battery, the electrolyte composition improves charge and discharge capacity and also increases battery lifespan by reducing the corrosion of an ion exchange membrane and a current collector.

Provided is a redox flow battery having lowered internal resistance. The redox flow battery is provided with a diaphragm, a bipolar plate, an electrode disposed between the diaphragm and the bipolar plate, an inlet port for supplying an electrolytic solution to the electrode, and an outlet port for evacuating the electrolytic solution from the electrode, and carries out charging-discharging reactions by flowing the electrolytic solution to the electrode. The electrode is provided with an anisotropic electrode layer having different permeabilities between a direction A1 in the plane of this electrode and a direction A2 that is orthogonal to the direction A1 in the plane of the electrode. In the anisotropic electrode layer, permeability K1 in the direction A1 is greater than permeability K2 in the direction A2. The electrode is disposed in such a way that the direction A1 is substantially parallel to the main flow direction of the electrolytic solution inside the electrode, which is determined based on the shape of the face of the bipolar plate toward the electrode, and the positional relationship between the inlet port and the outlet port.
