<p>One aspect of the present invention provides a redox flow battery minimizing heavy complexing bromine which overflows from a two phase electrolyte tank to a cathode electrolyte tank, and increasing efficiency. According to an embodiment of the present invention, the redox flow battery comprise a stack which generates current, and an electrolyte tank which supplies an electrolyte to the stack and stores the electrolyte spilled from the stack. The electrolyte tank comprises: an anode electrolyte tank accommodating an anode electrolyte supplied between a membrane of the stack and an anode electrode; the cathode electrolyte tank accommodating a cathode electrolyte supplied between the membrane of the stack and a cathode electrode, and connected to the anode electrolyte tank by a first overflow pipe; and the two phase electrolyte tank accommodating two phases of the cathode electrolyte spilled between the membrane and the cathode electrode, and connected to the cathode electrolyte tank by a second overflow pipe. The two phase electrolyte tank divides the inflow side and the outflow side of the cathode electrolyte, and additionally comprises a partition which is installed inside to form a communication port which communicates both sides at the bottom.</p> |
