Abstract: The present invention relates to a redox flow battery, and more particularly, provides a redox flow battery including: a stack in which positive electrode cells, separators, and negative electrode cells are repeatedly stacked from bipolar plates, and a bipolar plate, a collector, and an end plate are sequentially disposed on an outer side of each of the outermost positive electrode cell and the outermost negative electrode cell; a positive electrode electrolyte tank that stores positive electrode electrolyte to be supplied to the positive electrode cells; and a negative electrode electrolyte tank that stores negative electrode electrolyte to be supplied to the negative electrode cells. The positive and negative electrode electrolyte tanks include: an outflow pipe arrangement for transferring electrolyte to the stack; an inflow pipe arrangement for receiving the electrolyte from the stack; and an electrolyte injection hole for injecting electrolyte, introduced into the positive and negative electrode electrolyte tanks, to the inside of the redox flow battery. Thus, electrolyte after redox is uniformly injected into an electrolyte tank is thus efficiently mixed with electrolyte remaining the electrolyte tank and is then returned to a stack, to prevent charging capacity and energy efficiency from being reduced by overvoltage, thereby improving a battery performance.
