| titleOfInvention | Silicon-based composite negative electrode material for lithium ion battery and preparation method thereof |
| abstract | The invention provides a silicon-based composite negative electrode material for a lithium ion battery, which comprises a substrate and a nano silicon material array arranged on the substrate, wherein silicon and/or silicon oxide nanospheres are formed among gaps of the nano silicon material array. The silicon-based composite negative electrode material is fused with the one-dimensional silicon nano silicon material array and the three-dimensional silicon nanospheres, so that the volume effect of silicon can be fully reduced, the cycle performance is improved, the volume specific capacity can be improved, and the materials with various shapes are not easy to agglomerate. The invention also provides a preparation method of the silicon-based composite negative electrode material for the lithium ion battery. |
