A Si-porous carbon composite, prepared by the carbonization of clathrate compounds including nano-Si particles, was proposed as a new anode for Li-ion batteries offering the advantages of low manufacturing cost and better electrochemical properties. The porous carbon obtained from the clathrate compounds of α-cyclodextrin and surfactant had a high specific surface area of 2000 m2 g−1, and its initial delithiation capacity was 363 mAh g−1 at a rate of 0.1 C. In addition, the initial delithiation capacity of the obtained Si-porous carbon composite was 556 mAh g−1 at a rate of 0.1 C. In addition, its capacity retention was 96% after 100 cycles, because the low electronic conductivity of Si was improved by preparing the composites of Si and porous carbon.
