  A battery capable of improving 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. The electrolytic solution contains an ionic compound such as (2,2-difluoromalonate oxalate) lithium borate and [bis(3,3,3-trifluoromethyl)glycolate oxalate]lithium borate as an electrolyte salt. In the ionic compound, an anion has an asymmetric structure, and a ligand having an oxygen chelate structure in the anion has a halogen as an element. In the battery, the chemical stability of the electrolytic solution is improved, compared to a battery in which the electrolytic solution contains bis(oxalate) lithium borate or the like as an electrolyte salt.
