| titleOfInvention | A secondary battery, a manufacturing method thereof, and a device including the secondary battery. |
| abstract | The present invention relates to a secondary battery, a method for manufacturing the secondary battery, and a device including the secondary battery. Specifically, the secondary battery of the present application includes a negative electrode sheet, the negative electrode sheet includes a negative electrode current collector and a negative electrode film layer, and the negative electrode film layer includes a first negative electrode film layer and a second negative electrode. The first negative electrode film layer includes a film layer, and the first negative electrode film layer is installed on at least one surface of the negative electrode current collector and contains a first negative electrode active material, and the first negative electrode active material contains graphite and. The uniformity of the particle size of the first negative electrode active material is 0.4 to 0.6, the second negative electrode film layer is installed on the first negative electrode film layer, and the second negative electrode film layer is provided. The negative electrode active material is contained, the second negative electrode active material contains artificial graphite, and the uniformity of the particle size of the second negative electrode active material is 0.25 to 0.45. The secondary battery has a high energy density and can simultaneously achieve both good quick charge performance and cycle performance. [Selection diagram] Fig. 1 |
