Negative electrode and lithium ion secondary battery |
| abstract |
In the negative electrode of the present invention, the negative electrode current collector includes a substrate and a plurality of protrusions, and the protrusions are formed on the surface of the substrate. The negative electrode active material layer includes a columnar active material layer and a stacked active material layer containing an alloy-based negative electrode active material. The columnar active material layer includes one or more columns that extend outwardly from the surface of the protrusions. The stacked active material layer is formed by stacking a thin film in a zigzag manner on the substrate surface between the protrusions. By using this negative electrode, negative electrode deformation, and separation of the negative electrode active material layer from the negative electrode current collector are suppressed, and a lithium ion secondary battery that has excellent charge and discharge cycle performance and output performance can be obtained. |
