摘要： 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 versus 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, or a second maleic anhydride compound.

摘要： A secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution. The positive electrode includes primary particles that each include a lithium-manganese phosphate compound and that have an average particle diameter of less than or equal to 100 nm. The negative electrode has an electrochemical capacity per unit area of less than or equal to an electrochemical capacity per unit area of the positive electrode.
