摘要	Porous silicon carbon (Si@C) has been regarded as a promising candidate to overcome volume change of silicon-based anodes. However, the relationship between pore size distribution and properties of porous Si@C materials is not clear. Herein, porous materials with different pore size structures are synthesized by adjusting the proportion of LiCl additives in the template, which is used to study the effect of pore size distribution on the properties of batteries. The results show that the porous Si@C prepared with the content of 10% LiCl templates has the perfect electrochemical comprehensive performance. In addition, we have utilized the density functional theory (DFT) calculation methods to further study the effect of carbon defects on the material properties.
