▎ 摘　　要

NOVELTY - Preparing silicon-carbon nanocomposite involves using black talc and carrying out a reduction reaction on the mixture of the black talc, and the reducing metal under the action of a ball mill. USE - Method for preparing silicon-carbon nano-composite used in lithium-ion battery (claimed). ADVANTAGE - The silicon-carbon nano composite material has a layered morphology and a hierarchical pore structure, has good silicon-carbon interface stability, and widely applied to lithium electronic batteries.
