| Abstract: |
| Among the many anode materials for lithium-ion batteries, silicon is regarded as the most promising anode for next-generation high-energy-density batteries owing to its ultrahigh theoretical capacity (4200 mAh g-1). However, the drastic volume changes of silicon-based anode materials during cycling greatly limit its electrochemical performance and inhibit its practical applications. It has been shown that silicon/carbon composite anode materials can efficiently mitigate the volume expansion of silicon and contributed to enhanced conductivity, thus improving the stability of silicon-based anodes and the cycle life of the battery. However, achieving industrial production with high stability remains a great challenge. The chemical vapor deposition (CVD) has been widely used in the preparation of silicon/carbon anode materials owing to its high-quality deposition and simple process. In this review, we summarize application of CVD in silicon/carbon anodes for lithium-ion batteries from three aspect: deposited carbon, deposited silicon and deposited silicon/carbon. The synthesis methods of silicon/carbon composite anode materials and their own advantages and disadvantages are elucidated. Finally, the development trend and application outlook of silicon-based anodes are given. |
