Abstract:

Si-based anode material is regarded as a key material for improving the energy density of lithium-ion batteries due to its high specific capacity and low lithium-ion intercalation potential. However, its large volume expansion and side reactions with electrolyte will cause serious interfacial problems. This reviewer article starts from the definition of the Si anode interface, and then summarizes its interface problems, the corresponding causes and the formation mechanism. After that, the present development status of interface engineering of the Si-based anode is described. At last, the future research directions towards tackling the Si-based anode interface problems are concluded and proposed.

Key words: Lithium-ion battery, Silicon-based anode material, Interface engineering, Artificial interface, Composite material
