摘要:
A battery capable of improving battery characteristics such as cycle characteristics and high temperature storage characteristics is provided. An anode includes an anode active material which includes Sn or Si as an element. A separator is impregnated with an electrolyte solution, and the electrolyte solution includes an acid anhydride such as succinic anhydride or a derivative thereof. Thereby, a coating is formed on the anode, and the decomposition of the electrolyte solution in the anode can be prevented. An electrolyte solution to which 4-fluoro-1,3-dioxolane-2-one is mixed is more preferably used.
