| titleOfInvention | Silicon negative electrode sheet and preparation method thereof and lithium ion battery |
| abstract | The present invention provides a silicon negative electrode sheet, a preparation method thereof, and a lithium ion battery. The silicon negative electrode sheet includes a current collector, a silicon negative electrode undercoat layer and a silicon negative electrode active material layer that are sequentially stacked on the current collector. The fluid includes porous copper foil, and the raw material of the silicon negative electrode primer layer includes: silicon negative electrode active material, a conductive agent, a binder and a dispersant, wherein the conductive agent includes single-walled carbon nanotubes. The silicon negative electrode sheet provided by the invention can improve the cyclic expansion problem of the silicon negative electrode, and at the same time, without affecting the thickness, it can effectively increase the residual liquid amount of the silicon negative electrode system, and delay the drying of the electrolyte in the silicon negative electrode system during the cycle process. time to increase cycle life. |
