摘要：Silicon has been recognized as one of the most promising anode materials for lithium-ion batteries (LIBs) due to its high theoretical specific capacity and similar working voltage as the lithium anode. However, there are some unavoidable drawbacks including volume expansion effects, low conductivity, the constant formation of SEI during lithiation and delithiation contributes to its fewer possibilities for commercialization. Therefore, modification of silicon for better performance is required for future applications. This review demonstrates recent progress and development of modification for the silicon-based anode including silicon-carbon composite with yolk-shell structure, nanostructured silicon, and alloying method. Finally, the existing problems and future improvements are also discussed based on current development.
