摘要：
A battery capable of improving battery characteristics such as cycle characteristics is provided. An electrolytic solution is impregnated in a separator. The electrolytic solution contains 4-fluoro-1,3-dioxolane-2-one. Fluorine ion content in the electrolytic solution is preferably from 10 weight ppm to 3200 weight ppm. Thereby, chemical stability of the electrolytic solution is improved, and cycle characteristics are improved. The present invention is effective for the case using an anode active material containing Sn or Si as an element for an anode.
