Abstract
A secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution. The electrolytic solution includes a reactive cyclic carbonic acid ester compound and an anthraquinone compound. The reactive cyclic carbonic acid ester compound includes at least one of an unsaturated cyclic carbonic acid ester, a fluorinated cyclic carbonic acid ester, or a cyanated cyclic carbonic acid ester. The anthraquinone compound is represented by Formula (1).
Claims10
A secondary battery comprising:
- a positive electrode;
- a negative electrode;
- and
- an electrolytic solution, wherein the electrolytic solution includes
- a reactive cyclic carbonic acid ester compound including at least one of an unsaturated cyclic carbonic acid ester, a fluorinated cyclic carbonic acid ester, or a cyanated cyclic carbonic acid ester, and
- an anthraquinone compound represented by Formula (1),
- where
- each of R1 to R8 is independently one of a hydrogen, an alkyl group, an alkenyl group, an aryl group, or an acid metal salt group, and
- any two or more of RI to R8 are optionally bonded to each other, and
- at least one of R1 to R8 is an alkyl group, an alkenyl group, an aryl group, or an acid metal salt group.
