Lithium-ion secondary battery |
| abstract |
The present invention provides a lithium ion secondary battery comprising a positive electrode formed by arranging a positive electrode active material layer on a positive electrode current collector, a negative electrode formed by arranging a negative electrode active material layer on the negative electrode current collector, and an electrolyte, the positive electrode The active material layer contains a positive electrode active material containing a lithium-nickel composite oxide, the positive electrode contains an alkali component in an amount of less than 1% by weight of the positive electrode active material, and the electrolyte contains a cyclic carbonate additive containing an unsaturated bond The molar ratio of the cyclic carbonate additive having an unsaturated bond relative to the total molar amount of the additive is 78% or less. |
