Nonaqueous electrolyte secondary battery |
| abstract |
In a non-aqueous electrolyte secondary battery in which a SEI film is formed on the surface of a negative electrode active material, a technique capable of improving the performance of the battery more suitably is provided. A non-aqueous electrolyte secondary battery disclosed herein includes a positive electrode, a negative electrode, and a non-aqueous electrolyte, and has a LiBOB skeleton and a fluorosulfonic acid skeleton on the surface of a negative electrode active material. A negative electrode SEI film 29 including at least a positive electrode SEI film 19 including at least a phosphate skeleton is formed on the surface of the positive electrode active material 18. When the component amount of the LiBOB skeleton in the negative electrode SEI film 29 is IB, the component amount of the fluorosulfonic acid skeleton in the negative electrode SEI film 29 is IS, and the component amount of the phosphoric acid skeleton in the positive electrode SEI film 19 is IP. While satisfying the formula (1) represented by ≦ IB / IS ≦ 10 and the formula (2) represented by 5 μmol / m 2 ≦ IP ≦ 15 μmol / m 2, the BET specific surface area of the negative electrode active material is 3.5 m 2 / g or more. The component amount IB of the LiBOB skeleton is 4.3 μmol / m 2 or more. [Selection] Figure 3 |
