Abstract: Secondary batteries capable of improving cycle characteristics are provided. The secondary battery includes a cathode, an anode, and an electrolytic solution. A separator provided between the cathode and the anode is impregnated with the electrolytic solution. The electrolytic solution contains a solvent and an electrolyte salt. The solvent contains a cyclic compound having a disulfonic acid anhydride group (—S(═O)2—O—S(═O)2—) and at least one of a nitrile compound. Compared to a case that the solvent does not contain both the cyclic compound having the disulfonic acid anhydride group and succinonitrile or a case that that the solvent contains at least one thereof, chemical stability of the electrolytic solution is improved. Thus, even if charge and discharge are repeated, electrolytic solution decomposition is inhibited.
