Abstract Porous silicon/carbon (Si/C) anode materials for Lithium-ion batteries was synthesized successfully by hydrochloric acid etching and calcination method using micron Si-Al alloy as silicon source and phenolic resin as carbon source. The microstructure and morphology were characterized by XRD, SEM, TEM, XPS and BET. The electrochemical performance were measured by constant current charge-discharge test and EIS. The results show that Si/C is porous structure and its pores are distributed between 1-6 nm. The specific discharge specific capacity of Si/C is 1287.0 mAh/g at a current density of 100 mA/g after 50 cycles, corresponding to the capacity retention of 91.0% (for the second cycle). Si/C delivers a high specific discharge capacity of 605.9 and 359.0 mAh/g at 1 A/g and 2 A/g, respectively. The lithium ion diffusion coefficient of Si/C is 5.98×10-11 cm2 s−1, which is higher than that of 7.57×10-12 cm2 s−1 for porous Si.

Silicon/carbon (Si/C) composite anode materials are successfully synthesized by mechanical ball milling followed by pyrolysis method. The structure and morphology of the composite are characterized by X-ray diffraction and scanning electron microscopy and transmission electron microscope, respectively. The results show that the composite is composed of Si, flake graphite, and phenolic resin-pyrolyzed carbon, and Si and flake graphite are enwrapped by phenolic resin-pyrolyzed carbon, which can provide not only a good buffering matrix but also a conductive network. The Si/C composite also shows good electrochemical stability, in which the composite anode material exhibits a high initial charge capacity of 805.3 mAh g−1at 100 mA g−1and it can still deliver a high charge capacity of 791.7 mAh g−1when the current density increases to 500 mA g−1. The results indicate that it could be used as a promising anode material for lithium ion batteries.
