The cycling performance and stability of Si-SiOx@Cs are collected using Landt battery tester (CT2001A) under various current density between 0.005 and 2.5 V versus Li/Li + at room temperature with lithium metal as both counter and reference electrode. Li + diffusion coefficient of the anodes was determined by Galvanostatic Intermittent Titration Technique (GITT) with the titration time and rest time of 10 min and 2 h at 100 mA•g -1 , respectively. Si-SiOx@Cs/electrolyte/NMC111 full cell were cycled between 3.0 and 4.3 V under 100 mA•g -1 with the prelithiation process of Si-SiOx@Cs.
