  "textContent": "Provided is a battery capable of improving the chemical stability of an electrolyte and characteristics. The battery comprises a spirally wound electrode body (20) including a strip-shaped cathode (21) and a strip-shaped anode (22) spirally wound with a separator (23) in between. During charge, lithium metal is precipitated on the anode (22), so the capacity of the anode (22) is represented by the sum of a capacity component by insertion and extraction of lithium and a capacity component by precipitation and dissolution of the lithium metal. The separator (23) is impregnated with an electrolyte solution including an electrolyte salt. The electrolyte salt includes a first lithium salt LiN(CnF2n+1SO2)(CmF2m+1SO2) and a second lithium salt such as LiPF6 or the like. Thereby, the chemical stability of the electrolyte solution can be improved, and a side reaction can be inhibited, so charge-discharge cycle characteristics can be improved.",
