  "textContent": "The present application relates to the technical field of negative electrode materials for batteries, and in particular relates to a porous composite elastomer and silicon-carbon, and preparation methods therefor and the use thereof. The present application provides a porous composite elastomer, which has a porous structure and comprises a flexible body and a rigid body, which are interpenetrating, wherein a raw material of the flexible body comprises carbon nanotubes, and the rigid body comprises hard carbon. In the present application, a silicon-carbon composite material is prepared by using carbon nanotubes and hard carbon as carbon sources and compounding same with silicon; and compared with a conventional silicon-carbon composite material, the carbon nanotubes, serving as a bridge between the silicon and the hard carbon, effectively improve the conductivity and the ion conducting energy, thereby improving the rate performance of a negative electrode material.",
