In order to investigate the performance of Si-SiOx@C-1.25 in full cell, the prelithiated Si-SiOx@C-1.25 was used to pair with a NMC111 cathode to assemble full cell. As shown in Fig. , the full cell is cycled at 100 mA•g -1 with lithium metal and NMC111 as a control sample. The first five cycles are 50 mA•g -1 as an activation process. The initial capacity of Li metal-NMC111 cell is higher than Si-SiOx@C-1.25.
