The silicon-based particle includes a silicon-containing matrix and a polymer layer, and the polymer layer is located on a surface of at least a part of the silicon-containing matrix and contains carbon nanotubes and a transition metal element. A lithium-ion battery prepared from the negative active material has improved cycle performance, deformation resistance and rate performance and reduced impedance.",
