| titleOfInvention | Method for preparing sub-nano silicon carbon composite material by liquid phase method |
| abstract | The invention discloses a method for preparing a sub-nano silicon carbon composite material by a liquid phase method, comprising the following steps: step (1), dissolving small molecular silane and ethylenediamine in conventional In the organic solvent, stir at room temperature for 5-10 hours to obtain a yellow solution; step (2), mix the yellow solution in step (1) with Grignard reagent, stir at room temperature for 2 hours, and purify to obtain a silicon group modified by an organic group Cluster mixed solution; in step (3), the mixed solution in step (2) is decompressed and drained to obtain a yellow solid, and placed in a tube furnace, under the protection of flowing high-purity argon, in a temperature range of 500-1000 ° C The yellow solid is heat-treated, and the sub-nanometer silicon-carbon composite material is prepared after cooling. The method of the invention has the advantages of mild reaction conditions, easy amplification and regulation, is expected to be used for industrialized preparation of sub-nanometer silicon-carbon composites, and can be applied in the field of energy, especially in the field of lithium ion batteries. |
