| titleOfInvention | Porous silicon/silicon-carbon composite material and preparation method and application thereof |
| abstract | The invention discloses a preparation method of a porous silicon/silicon-carbon composite material, which comprises the following steps: step 1: placing magnesium silicide and a precursor in a reaction container at a certain distance, wherein the magnesium silicide and the precursor are arranged along the inert gas inlet flow direction of the reaction container; step 2: introducing inert gas into the reaction vessel, heating the reaction vessel to perform a magnesium thermal reaction, and obtaining a porous silicon/silicon-carbon composite material crude product after the reaction is finished; and step 3: and (3) carrying out acid washing, water washing and drying on the porous silicon crude product obtained in the step (2) to obtain the porous silicon/silicon carbon composite material. The invention also discloses the porous silicon or silicon-carbon composite material prepared by the preparation method and application of the porous silicon or silicon-carbon composite material as a lithium ion negative electrode material. The porous silicon or silicon-carbon composite material prepared by the invention has excellent cycle performance and rate capability in a lithium ion battery, and simultaneously has the advantages of simple and easy preparation method, contribution to batch preparation and the like. |
