    Abstract: A battery 1000 according to the present disclosure includes a first electrode 101, a second electrode 103, and an electrolyte layer 102 positioned between the first electrode 101 and the second electrode 103. The first electrode 101 includes a current collector 100 and an active material layer 104 positioned between the current collector 100 and the electrolyte layer 102. The active material layer 104 includes an alloy, and the alloy includes Bi and Mn. A method for producing an electrode according to the present disclosure includes: forming a plating layer on a current collector by electroplating, the plating layer including a Bi plating film and a Mn plating film; and heating the current collector and the plating layer to obtain an electrode in which an active material layer including an alloy is formed on the current collector, the alloy including Bi and Mn.

    Abstract: A flow battery includes: a first liquid containing dissolved therein a condensed aromatic compound and lithium; a first electrode immersed in the first liquid; and a first circulator including a first container and a first passage prevention member. The first liquid containing the condensed aromatic compound dissolved therein has the property of causing the lithium to release solvated electrons and dissolve as cations. When the lithium dissolved in the first liquid precipitates on the first electrode, lithium precipitate particles are generated. The first circulator circulates the first liquid between the first electrode and the first container. The first circulator transfers the lithium precipitate particles generated on the first electrode to the first container. The first passage prevention member is disposed in a channel through which the first liquid flows from the first container to the first electrode. The first passage prevention member prevents passage of the lithium precipitate particles.

    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.

    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.
