Practical Applications

Silicon (Si) has been considered as one of the most promising anode materials in lithium-ion battery. However, practical applications of Si are hindered by undesirable cycling stability resulting from poor electrical conductivity and huge volumetric change during cycling process. Here, we prepared a yolk-shell silicon/carbon composite by etching carbon-coated heat-treated silicon monoxide (SiO) precursor. The as-prepared Si/SiOx@Void@C composite of inner silicon/silicon oxides and outer carbon shell with voids between them (Si/SiOx@Void@C), shows impressive cycling stability (1020[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 1[Formula: see text]A[Formula: see text]g[Formula: see text] over 200 cycles) and excellent rate performance (775[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 6[Formula: see text]A[Formula: see text]g[Formula: see text]). The remarkable electrochemical performance is due to the enhanced electrical conductivity originated from the carbon shell and the volume buffer effect of the yolk-shell structure. A combination of the yolk-shell structure with Si/C composites is believed to be a promising way to improve the performance of Si-based materials in lithium-ion batteries.
