| description | The invention discloses a multi-dimensional carbon-based slurry silicon-based negative electrode material as well as a preparation method and application thereof. The multi-dimensional carbon-based slurry comprises 1-10 parts of a conductive agent, 0.5-15 parts of a dispersing agent and 80-95 parts of a solvent, the silicon-based negative electrode material comprises a silicon-based active substance, a pyrolytic carbon coating layer and a multi-dimensional carbon-based material coating layer, and is prepared by taking multi-dimensional carbon-based slurry as a raw material. The multidimensional carbon-based slurry provided by the invention solves the problem of dispersity of a carbon material in the slurry, and has good dispersity and stability; the silicon-based negative electrode material has a double-layer multi-element conductive network, has high conductivity and mechanical stability, and can inhibit volume expansion of silicon, reduce side reaction and ensure excellent electrochemical performance of the |
