| titleOfInvention | A kind of negative electrode current collector and its preparation method and application |
| abstract | The invention provides a negative electrode current collector and a preparation method and application thereof. A first aspect of the present invention provides a negative electrode current collector, the negative electrode current collector includes a metal layer and a conductive layer disposed on the upper surface and/or the lower surface of the metal layer; the conductive layer includes a binder and a metal tube , wherein the metal tube includes an inner first metal layer and an outer second metal layer, the first metal layer includes a lithiophilic metal, and the second metal layer includes a lithiphobic metal. The negative electrode current collector provided by the present invention includes a metal tube, and the inside of the metal tube can provide an effective lithium storage space, and the metal tube structure of the inner lithiophilic layer and the outer lithophobic layer can induce the deposition of metal lithium inside the metal tube, thereby increasing the metal Uniformity of Li deposition, thereby improving the cycling performance and safety performance of Li-ion batteries. |
