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.
