Abstract
[Problem] To provide a means in which durability (cycle durability, storage durability) and input/output characteristics (cell internal resistance) of a battery can be improved at the same time, while hardly being affected by specifications of the active material that is used to configure the battery, in a nonaqueous electrolyte secondary battery such as a lithium ion secondary battery (10, 50). [Solution] In a nonaqueous electrolyte secondary battery having a power-generating element (21, 57) comprising a positive electrode made by a positive electrode active material layer (15) containing a positive electrode active material being formed on a surface of a positive electrode current collector (12), a negative electrode made by a negative electrode active material layer (13) containing a negative electrode active material being formed on a surface of a negative electrode current collector (11), and a separator (17) containing an electrolyte, the electrolyte contains an electrolyte salt, a nonaqueous solvent into which the electrolyte salt can be dissolved, a first additive selected from predetermined oxalate compounds and disulfonic acid ester compounds, and a second additive that has a reduction potential less than the reduction potential of the first additive, and that is selected from a group comprising vinylene carbonate, fluoroethylene carbonate, vinyl ethylene carbonate, 1, 3-propane sultone, 1, 4-butane sultone, 1, 3- propene sultone, succinonitrile, and adiponitrile; and, if the BET specific area of the negative electrode active material is SSA [m2/g], the ratio (liquid coefficient) of the electrolyte amount to the total void volume of the positive electrode, the negative electrode, and the separator is L, the ratio of the addition amount of the first additive to the total amount of the nonaqueous solvent and the electrolyte salt in the electrolyte is A [mass%], and the ratio of the addition amount of the second additive to the total amount of the nonaqueous solvent and the electrolyte salt in the electrolyte is B [mass%], 0.21 ? A x L/SSA ? 0.69 and 0.51 ? B x L/SSA ? 1.5 are satisfied.
