Silicon monoxide (SiO)-based negative materials have attracted widespread attention due to the low working potential and high specific capacity. However, the large volume dilation (about 200%) is adverse to the electrochemical performance of battery during the charge-discharge process. To overcome the disadvantage of volume change, much effort has been paid to minimize the volume expansion. Unfortunately, the volume change is inescapable no matter how to modify the SiO-based materials. Therefore, utilizing the characteristics of volume expansion to improve the electrochemical properties of SiO...
