Novel liquid phase displacement method was developed to prepare a silicon/carbon composite (Si/C) by directly reacting nano silicon (which was synthesized by magnesium thermal reduction of SiO2) and glucose. Subsequently, When the Si/C is used as the anode material for LIBs, the batteries display favorable discharge capacities (800 mAh/g after 50 cycles at 100 mA/g), high-rate performance (385 mAh/g at 4 200 mA/g), and excellent stable cyclability (459 mAh/g after 120 cycles at 840 mAh/g). Which is much higher than the discharge capacity of pure silicon and carbon. Such results indicate that the intervention of carbon effectively conductivity improves of Si for the lithium storage performance increasing. Notably, the research might provide a new strategy for the application of Si/C composite materials in high-performance LIBs.
