Abstract:

Secondary lithium-ion battery(LIB) plays an important role in our daily life, however, state-of- the-art LIBs cannot meet the high-energy-density demand of electric vehicles and large-scale gird, developing high-capacity electrode materials is a must. Recently, Si anode has attracted much attention due to its high theoretical specific capacity, low electrochemical potential, and abundance in the earth’s crust, but the large volume change(ca. 300%) during cycling and low initial Coulombic efficiency(ICE) severely hinder its practical applications. Prelithiation as a promising strategy has been proven effective to improve the ICE for high- performance Si-based anodes. This review focuses on demonstrating the scientific significance of prelithiation, systemically introducing various methods of prelithiation by recent advances and analyzing their own advan- tages and disadvantages, and finally proposing the challenges and prospects of the prelithiation of Si-based anodes.

Key words: Si anode, Initial Coulombic efficiency, Prelithiation, High-performance Si-based anode
