Abstract
The invention relates to a silicon-based anode material for a lithium-ion battery, a preparation method therefor, and a battery. The silicon-based negative electrode material is prepared by the compounding of 90 wt %-99.9 wt % of a silicon-based material and 0.1 wt %-10 wt % of carbon nanotubes and/or carbon nanofibers which grow on the surface of the silicon-based material in situ.
