    Abstract: A flow battery includes a negative electrode, a positive electrode, a first liquid including first redox species, a second liquid, and a lithium ion conductive membrane. At least one selected from the group consisting of the first liquid and the second liquid includes a supporting electrolyte including lithium. The total of the number of moles of lithium dissolved in the first liquid and the number of moles of lithium dissolved in the second liquid is larger than the number of moles of lithium present in the supporting electrolyte. 0.2≤(M1+M2−M3)/M4≤1.5 wherein M1 is the number of moles of lithium dissolved in the first liquid, M2 is the number of moles of lithium dissolved in the second liquid, M3 is the number of moles of lithium present in the supporting electrolyte, and M4 is the number of moles of the first redox species.

    Abstract: A redox flow battery includes a negative electrode; a positive electrode; a first liquid which contains a first nonaqueous solvent, a first redox species, and metal ions and which is in contact with the negative electrode; a second liquid which contains a second nonaqueous solvent and which is in contact with the positive electrode; and a metal ion-conducting membrane which is disposed between the first liquid and the second liquid and which is nonporous. The metal ion-conducting membrane is swollen by at least one selected from the group consisting of the first liquid and the second liquid and allows the metal ions to pass therethrough.

    Abstract: The lithium secondary battery of the present invention satisfies at least one requirement selected from the group consisting of requirements (i) and (ii). (i) An electrolyte liquid includes an anode mediator which is dissolved along with lithium in a solvent of the electrolyte liquid to give, to the electrolyte liquid, an equilibrium potential which is not more than an upper limit potential at which a compound of lithium and an anode active material is formed, and does not include a compound which is dissolved along with lithium in the solvent of the electrolyte liquid to give, to the electrolyte liquid, an equilibrium potential which is more than the upper limit potential. (ii) The electrolyte liquid only includes, as the anode mediator, only a compound which is dissolved along with lithium in the solvent of the electrolyte liquid to give, to the electrolyte liquid, the equilibrium potential which is not more than the upper limit potential at which the compound of lithium and the anode active material is formed.

    Abstract: A flow battery includes: a cell including a first chamber and a second chamber a first liquid that contains a charge mediator and a discharge mediator, and that is located in the first chamber of the cell; a first electrode located in the first chamber of the cell; a first active material that is solid and that is located in the first chamber of the cell; a second liquid located in the second chamber of the cell; a second electrode that is located in the second chamber of the cell, and that is a counter electrode to the first electrode; and a first stirrer that stirs the first liquid in the first chamber. The charge mediator has a lower equilibrium potential than an equilibrium potential of the first active material. The discharge mediator has a higher equilibrium potential than the equilibrium potential of the first active material.
