| titleOfInvention | Biological carbon/silicon nano material, preparation method thereof and application of biological carbon/silicon nano material as lithium ion battery cathode |
| abstract | The invention discloses a biochar/silicon nano material, a preparation method thereof and application of the biochar/silicon nano material as a lithium ion battery cathode, wherein biochar is ground into powder and is mixed with ionic liquid and stirred uniformly to obtain viscous solution; then adding an organic solvent for dilution, and continuously stirring to obtain a uniform mixed solution; then adding the nano silicon particles, stirring to uniformly disperse the nano silicon particles, and drying to obtain a solid mixture; and heating the solid mixture to 400-800 ℃, carrying out constant-temperature treatment for 2-4 h, cooling to room temperature, grinding into powder, and sieving to obtain the catalyst. According to the invention, the ionic liquid is adopted to dissolve the biomass charcoal, then the biomass charcoal and the nano-silicon form a two-layer coating structure through a one-step method, and the silicon dioxide in the middle layer is derived from the biomass charcoal, so that the preparation method does not need external additives and complicated steps, does not generate resource waste, does not have secondary pollution, and is non-toxic and harmless. The lithium ion battery prepared by the cathode material provided by the invention has the advantages of stable improvement of specific capacity, small impedance and excellent electrochemical performance. |
