Abstract
A redox flow battery includes a positive electrolyte containing a positive electrode active material and a negative electrolyte containing a negative electrode active material. A liquid amount of the positive electrolyte is different from a liquid amount of the negative electrolyte. Of the positive electrolyte and the negative electrolyte, a liquid amount ratio of the electrolyte larger in liquid amount to the electrolyte smaller in liquid amount is not lower than 1.05 and not higher than 5.0. A state of charge of a mixture electrolyte which is a mixture of the positive electrolyte and the negative electrolyte at a ratio equal to the liquid amount ratio is equal to or higher than 2%.
