Abstract
A battery capable of obtaining the high energy density and obtaining the superior cycle characteristics is provided. In an anode, the thickness of a single face of an anode active material layer containing a carbon material as an anode active material is from 75 μm to 120 μm. An electrolytic solution contains difluoroethylene carbonate as a solvent. Thereby, the energy density of the anode is improved, and the diffusion and the acceptance of lithium ions in the anode are improved.
