  • Electrolyte solution for redox flow battery containing organic active material and redox flow battery using the same
    Patent number: 10522863
    Abstract: This invention relates to an electrolyte solution for a redox flow battery containing an organic active material, in which an organic compound useful as a single active material for a cathode and an anode is dissolved in a water-soluble solvent, and to a redox flow battery using the same. The electrolyte solution of the invention is an aqueous electrolyte solution obtained by dissolving an active material in an aqueous solvent, and is thus very stable due to the low risk of fire or explosion. Furthermore, the organic compound is applied as a single active material to the cathode and the anode, and thus, when the capacity of the battery is decreased due to the permeation of the active material through the separator, the battery capacity can be restored through rebalancing.
