Beschreibung
Zusammenfassung:	Provided is a redox-flow battery system, etc., for which even when using a high concentration vanadium electrolyte, it is possible to stably obtain high energy density and battery capacity based on that concentration. The present invention is a redox-flow battery system 1 for performing charge and discharge by circulating an electrolyte that contains vanadium as an active material in a battery cell 2, wherein the electrolyte contains a dissolved vanadium compound and a vanadium compound dispersed in particle form, the total of the vanadium concentration of both vanadium compounds is 1.7 mol/L or more, and provided in the circulation route in which the electrolyte solution circulates are particle size adjusting means 16, 26 for adjusting the particle size of the vanadium compound dispersed in particle form to be smaller.
