摘要： A battery capable of obtaining a high energy density and obtaining superior cycle characteristics is provided. The thickness of a cathode active material layer is from 100 μm to 130 μm. The thickness of an anode active material layer is from 85 μm to 120 μm, and the volume density of the anode active material layer is from 1.7 g/cm3 to 1.85 g/cm3. An electrolytic solution contains 4-fluoro-1,3-dioxolane-2-one. Thereby, even when the thicknesses of the cathode active material layer and the anode active material layer are increased, the diffusion and acceptance of lithium in an anode are improved, and superior cycle characteristics can be obtained.
