Abstract
Provided is a lithium secondary battery comprising a cathode, an anode, and a non-aqueous electrolyte having lithium ion conductivity. A lithium metal is precipitated on a surface of the anode during charge of the lithium secondary battery. The lithium metal is dissolved from the surface of the anode in the non-aqueous electrolyte during discharge of the lithium secondary battery. The non-aqueous electrolyte contains a solvent and a lithium salt. The solvent includes a fluorinated ether. The fluorinated ether has a fluorination ratio of more than 0% and not more than 60%.
