Original Abstract Submitted
A secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution. The electrolytic solution includes a first electrolyte salt and a second electrolyte salt. The first electrolyte salt includes a first anion and a first cation. The second electrolyte salt includes a second anion and a second cation. The first anion includes at least one of a first imide anion represented by Formula (1), a second imide anion represented by Formula (2), a third imide anion represented by Formula (3), or a fourth imide anion represented by Formula (4). The second anion includes at least one of a hexafluorophosphate ion (PF), a tetrafluoroborate ion (BF), or a bis(fluorosulfonyl)imide ion (N(FSO)). A sum of a content of the first cation in the electrolytic solution and a content of the second cation in the electrolytic solution is greater than or equal to 0.7 mol/kg and less than or equal to 2.2 mol/kg. A ratio of a number of moles of the second anion in the electrolytic solution to a number of moles of the first anion in the electrolytic solution is greater than or equal to 13 mol % and less than or equal to 6000 mol %.
