LITHIUM ION SECONDARY BATTERY |
| 摘要 |
A lithium ion secondary battery includes: an electrode mixture layer that contains an electrode active material and an organic ferroelectric having a dielectric constant of 25 or higher; and an electrolytic solution that contains lithium bis(fluorosulfonyl)imide and a nonaqueous solvent. A content of the organic ferroelectric is 0.5 parts by mass to 10 parts by mass with respect to 100 parts by mass of the electrode active material. A proportion of a high-polarity solvent having a dielectric constant of 10 or higher in the nonaqueous solvent is 10 vol % or lower. |
