PROBLEM TO BE SOLVED: To provide a flow battery having high discharge potential.SOLUTION: The flow battery includes: a first liquid in which a first electrode mediator is dissolved; a first electrode immersed in the first liquid; a first active material immersed in the first liquid; and a first circulation mechanism for circulating the first liquid between the first electrode and the first active material. The first electrode mediator contains a tetrathiafulvalene derivative, and in the tetrathiafulvalene skeleton of the tetrathiafulvalene derivative, substituents are bonded to 4, 4 'and 5, 5' positions in a chain.SELECTED DRAWING: Figure 1 【課題】従来技術においては、高い放電電位を有するフロー電池の実現が望まれる。【解決手段】フロー電池は、第１電極メディエータが溶解した第１液体と、前記第１液体に浸漬される第１電極と、前記第１液体に浸漬される第１活物質と、前記第１電極と前記第１活物質との間で前記第１液体を循環させる第１循環機構と、を備え、前記第１電極メディエータは、テトラチアフルバレン誘導体を含み、前記テトラチアフルバレン誘導体のテトラチアフルバレン骨格の４，４'位および５，５'位には、鎖状に置換基が結合している。【選択図】図１
