| titleOfInvention | Lithium ion secondary battery |
| abstract | A lithium ion secondary battery is provided with a high output in a low charge state. A lithium ion secondary battery includes a positive electrode current collector and a porous positive electrode active material held by the positive electrode current collector. A material layer 223. Here, the positive electrode active material layer 223 includes, for example, positive electrode active material particles 610, a conductive material 620, and a binder 630. In the lithium ion secondary battery 100, the positive electrode active material particles 610 penetrate the shell 612, the shell 612 made of a lithium transition metal oxide, the hollow 614 formed inside the shell 612, and the shell 612. And a through hole 616. In the lithium ion secondary battery 100, the ratio of the hollow portion 614 to the average cross-sectional area of the positive electrode active material particles 610 in the average of the positive electrode active material layer 223 is 23% or more. Furthermore, the thickness of the shell 612 is 2.2 μm or less in the average of the positive electrode active material layer 223. [Selection] Figure 9 |
