| titleOfInvention | Composite negative pole piece and preparation method thereof, and lithium ion battery |
| abstract | The invention relates to a composite negative electrode pole piece and a preparation method and application thereof. The composite negative electrode pole piece has a carbon fiber-lithium-containing metal self-supporting structure; the carbon fiber-lithium-containing metal self-supporting structure includes a three-dimensional skeleton and spaces filled in the skeleton. The lithium-containing metal, the mass ratio of the three-dimensional framework to the lithium-containing metal is 1-15:5; the three-dimensional framework includes carbon fibers with a mass ratio of 50-80:10-40:1-5:0-5 , polymers, surfactants and tougheners. The composite negative pole piece of the present invention has the characteristics of light weight and high strength by filling metal lithium in the three-dimensional framework, and the battery assembled with the composite negative pole piece also has good cycle stability and cycle life. To a certain extent, the growth of lithium dendrites can be inhibited, and at the same time, it has good interfacial properties with the electrolyte. |
