Abstract: The inhomogeneous nature of SiO x anode material on the atomic scale directly affects its electrochemical performance. A large irreversible capacity loss at the first cycle severely hinders the applications of SiO x materials in lithium ion batteries. The modification of SiO x by means of high-energy ball-milling and wet alkali chemical reaction can tune the ordering of amorphous silicon and silicon dioxide in SiO x materials, which is beneficial to the activation of nano silicon region and the surficial composition optimization of the lithiated products of SiO x during the first discharge process, and the formed Li 2 SiO 3 phase and the increased O/Si ratio in the surface of SiO x contribute to the improved cyclic performance. This surface regulation approach is quite simple, efficient and suitable for large-scale applications of high-performance SiO x anode material. [Display omitted] • The SiO x was modified via high-energy ball milling and wet-alkali chemical reaction. • The Li + ions as network modifier contributes the surface structural recombination of SiO x. • The changes in SiO x surface chemistry optimize the lithiated products of SiO x. • The increased O/Si ratio of SiO x improves the cycling performance.
