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.

The battery includes: a spirally wound electrode body in which a cathode having a cathode active material layer on a strip-shaped cathode current collector and an anode having an anode active material layer on a strip-shaped anode current collector are layered with a separator in between, and spirally wound in a planular state; and a lead jointed to the cathode current collector or the anode current collector in a center portion of the spirally wound electrode body. An inner circumferential end of the cathode active material layer is provided in a region where the inner circumferential end does not overlap with the lead in a short axis direction of the spirally wound electrode body.

摘要： An electrolytic solution capable of improving battery characteristics even at high temperature, and a battery using the electrolytic solution are provided. A separator is impregnated with an electrolytic solution. The electrolytic solution includes a cyclic imide salt such as 1,1,2,2,3,3-hexafluoropropane-1,3-disulfonimide lithium and a light metal salt such as difluoro[oxalato-O,O′] lithium borate or bis[oxalato-O,O′] lithium borate. Thereby, the decomposition reaction of the electrolytic solution can be prevented even at high temperature, and the battery characteristics can be improved.
