摘要： A redox flow battery includes: a negative electrode; a positive electrode; a first liquid which is in contact with the negative electrode, and which contains a first nonaqueous solvent, a first redox species, and metal ions; a second liquid which is in contact with the positive electrode, and which contains a second nonaqueous solvent, a second redox species, and metal ions; and a metal ion-conducting membrane disposed between the first liquid and the second liquid. The metal ion-conducting membrane contains an organic polymer containing a plurality of hydroxy groups. The organic polymer contains a group formed by substituting at least a portion of the hydroxy groups with a metal sulfonate.
