    摘要： A secondary battery includes: a cathode; an anode; and an electrolytic solution. The anode includes an anode active material layer on an anode current collector. The anode active material layer includes a carbon material. The anode active material layer has a thickness from about 30 micrometers to about 100 micrometers both inclusive. The electrolytic solution includes an unsaturated cyclic ester carbonate represented by the following Formula (1) (X is a divalent group in which m-number of >C═CR1R2 and n-number of >CR3R4 are bonded in any order. Each of R1 to R4 is one of a hydrogen group, a halogen group, a monovalent hydrocarbon group, a monovalent halogenated hydrocarbon group, a monovalent oxygen-containing hydrocarbon group, and a monovalent halogenated oxygen-containing hydrocarbon group. Any two or more of the R1 to the R4 are allowed to be bonded to one another. m and n satisfy m≧1 and n≧0).

    摘要： A battery capable of improving the storage characteristics and the cycle characteristics is provided. The battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution is impregnated in a separator provided between the cathode and the anode. A solvent of the electrolytic solution contains a given sulfone compound such as bis(trimethylsilyl)-2,2-difluorosulfoacetate. Compared to a case that a solvent does not contain the foregoing sulfone compound, the chemical stability of the electrolytic solution is improved, and the decomposition reaction of the electrolytic solution is suppressed.
