| titleOfInvention | Lithium ion battery tab with grid structure design and preparation method thereof |
| abstract | The invention provides a lithium ion battery tab with a gridding structure design and a preparation method thereof. The lithium ion battery tab comprises at least one main tab, the main tab is of a composite layer structure and comprises at least one base film layer and at least one current collector layer, and the current collector layer covers the surface of one side or two sides of the base film layer; the two ends of the current collector layer along the current path are full-coverage areas of a conductive material full-coverage design, and a gridding area is arranged in the middle of the current collector layer; and a plurality of current collector modules are arranged in the gridding area, and the current collector modules and the full coverage area are communicated through a grid bridge. When a short circuit occurs in the battery, the internal resistance of the base film layer can be increased along with the rise of the temperature, heat is released, the grid bridge in the gridding area of the main tab is fused by heating, and a circuit is cut off, so that the occurrence of serious accidents is reduced. |
