Negative electrode and secondary battery |
| abstract |
There is provided a negative electrode including a negative electrode current collector and a negative electrode active material layer provided on the negative electrode current collector. In the negative electrode, the negative electrode active material layer includes a first layer having contact with the negative electrode current collector, and a second layer formed on the first layer. Further, the first and second layers are formed of carbon materials capable of inserting and extracting lithium. A specific surface area of a carbon material forming the second layer is larger than a specific surface area of a carbon material forming the first layer, and a thickness of the first layer corresponds to from 40% or more to 90% or less of a thickness of the entire negative electrode active material layer. |
