Abstract:
A secondary battery includes: a cathode; an anode; and an electrolytic solution. The anode includes a carbon material and styrene-butadiene rubber. 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.)
