ORGANIC ELECTROLYTE SOLUTION AND REDOX FLOW BATTERY COMPRISING THE SAME

摘要

PURPOSE: An organic electrolyte for a redox flow battery is provided to have a high energy density by increasing a solubility of the electrolyte. CONSTITUTION: An organic electrolyte comprises: a solvent; an electrolyte which consists of a metal-ligand coordination compound; and a polymeric compound which has metal affinity group as an additive. The additive is included as a quantity of 1-15 volume % of the organic electrolyte. In addition, a redox flow battery includes: an anode cell which includes an anode and an anolyte; a cathode cell which includes a cathode and a catholyte; an ion exchange membrane which is positioned between the anode cell and the cathode cell; and one or more of the anolyte and the catholyte are the organic electrolyte.
