In recent years,with the wide application of lithium-ion batteries,higher requirements have been put forward for battery performance and safety.As a kind of lithium ion battery material with high specific capacity,silicon-based anode material possesses high research and application value.However,it is faced with problems such as large volume change,unstable formation of solid electrolyte film(SEI)and poor conductivity,which limit its further study.Electrospinning is one of the commonly used methods in the fabrication of nanofibers,which provides an effective method for solving the problems existing in silicon-based materials.The purpose of this work is to systematically summarize and analyze the application of electrospinning technology in the preparation of silicon carbon composite anode materials for lithium ion batteries.Firstly,the basic principle and development process of electrospinning technology are briefly introduced.Then,the application of electrospinning technology in the structure of silicon carbon composite anode materials is summarized,including the preparation of silicon nanofibers,core-shell structures and porous structures.Finally,the current research progress is reviewed,and the future development direction of electrospinning technology in the field of silicon-carbon composite anode materials for lithium-ion batteries is prospected.
