The silicon-based anode materials are of great importance for lithium ion batteries ( LIBs) because of their high capacity. This paper reviews the latest research achievements of the silicon, silicon-metal alloys, silicon-carbon composites and other composite materials as anodes materials and discusses their research and application prospects. It also analyzes the existing problems of pure silicon anodes and focuses mainly on the novel silicon based anode materials. Regarding future research and application, the predominant direction will be to promote both cycle performance and electrochemical performance through the comprehensive application of nanocrystallization, amor-phization, alloying and compounding of silicon-based materials.
