| titleOfInvention | A kind of current collector and its application |
| abstract | The invention provides a current collector and its application. The current collector of the present invention includes an intermediate layer and a first conductive layer and a second conductive layer arranged on the two functional surfaces of the intermediate layer, and the intermediate layer includes a polymer with a linear thermal expansion coefficient α≥10-5 K -1 at 25°C and foam materials. Since the intermediate layer includes a foam material and a polymer, when the temperature of the battery rises to a critical temperature, the foam material will expand the polymer, thereby significantly expanding the intermediate layer, so that the first conductive layer and/or the second conductive layer are Peeling off the middle layer can cut off the internal current path of the battery, prevent thermal runaway inside the battery, and significantly improve the safety performance of the battery. |
