  "textContent": "A lithium-ion secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution. The negative electrode includes a negative electrode active material having a reaction potential of 0.5 V or higher than a lithium electrode, and has an electrochemical capacity per unit area of less than or equal to an electrochemical capacity per unit area of the positive electrode. The electrolytic solution includes a solvent, an electrolyte salt, and at least one of a diphenyl carbonate compound, an unsaturated cyclic carbonate ester, a first maleic anhydride compound, and a second maleic anhydride compound.",
