POROUS SILICON BASED NEGATIVE ELECTRODE ACTIVE MATERIAL, METHOD FOR MANUFACTURING THE SAME, AND RECHARGEABLE LITHIUM BATTERY INCLUDING THE SAME |
| 摘要 |
The present invention relates to a method of preparing a porous silicon-based negative electrode active material comprising: mixing a porous silica (SiO2) and an aluminum powder; oxidizing all or part of the aluminum powder as an aluminum oxide while at the same time reducing all or part of the porous silica as a porous silicon (Si) by heat-treating a mixture of the porous silica with the aluminum powder, a negative electrode active material, and a rechargeable lithium battery including the same. |

1. A method of preparing a porous silicon-based negative electrode active material, comprising:
mixing a porous silica (SiO2) with an aluminum powder; oxidizing all or part of the aluminum powder to an aluminum oxide as soon as reducing all or part of the porous silica to a porous silicon (Si) by heat-treating a mixture of the porous silica with the aluminum powder. |
