Si/C nanocomposite was successfully prepared by a scalable approach through high-energy mechanical milling and carbonization process. The crystalline structure of the milled powders was studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM). Morphology of the milled powders was investigated by Field-emission scanning electron microscopy (FE-SEM). The effects of milling time on crystalline size, crystal structure and microstructure, and the electrochemical properties of the nanocomposite powders were studied. The nanocomposite showed high reversible capacity of ~1658 mAh/g with an initial cycle coulombic efficiency of ~77.5%. The significant improvement in cyclability and the discharge capacity was mainly ascribed to the silicon particle size reduction and carbon layer formation over silicon for good electronic conductivity. As the prepared nanocomposite Si/C electrode exhibits remarkable electrochemical performance, it is potentially applied as a high capacity anode material in the lithium-ion secondary batteries.

Silicon/carbon anode materials of different proportions for lithium ion battery were prepared by high energy ball milling. The composites were characterized using X-ray diffraction (XRD), and scanning electron microscope (SEM). The electrochemical performance of the composites was tested by means of galvanostatic testing system. The results indicated that the initial reversible capacity reached to 2162 mAh•g-1, which was much larger than the theoretical capacity of carbon negative materials at the ratio of 6:4 (Si: C). The capacity maintained to 1042 mAh•g-1 after 50 cycles. High capacity and good cycle property of the Si/C composites revealed that they were potential to take the place of the traditional carbon anode materials.

Ball Milling Time

Silicon material possesses the highest theoretic capacity (4200mAh/g, ten times of the capacity of commercialized carbon anode materials) of all known anode materials for lithium ion batteries and thus receives lots of attention to date. Silicon-containing composite electrode for lithium ion batteries was prepared by high-energy ball milling process. The microstructure and morphology of silicon electrode was investigated in detail. The effect of the structure transformation of the electrode by ball milling on the electrochemical behavior was systematically analyzed. Electrode precursors after a mediate ball milling time of 45min is beneficial to get a better cycling performance, due to the well distributed and less destroy of Carboxyl Methyl Cellulose (CMC). Weak lithium insertion into CMC occurs unavoidably in the charging-discharging process of the composite electrodes, which should be the main reason for the sudden disability of electrode. The electrochemical properties can get a dramatic enhancement within voltage window of 0.02-1.5V. Excellent cyclability with high capacity retention above 1800mAh/g after 40 cycles could be gained by controlling the ball-milling time and the voltage windows. It might be a feasible way to obtain satisfactory cyclability for high capacity anode materials.

Lithium alloying compounds as an anode materials have been a focused for high capacity lithium ion battery due to their highenergy capacity and safety characteristics. Here we report on the preparation of graphite-tin composite by using ball-milling in liquid media. The composite material has been characterized by scanning electron microscope, energy depressive X-ray spectroscopy, X-ray diffraction and Raman spectra. The lithium-ion cell made from graphite-tin composite presented initial discharge capacity of 1065 mAh/g and charge capacity 538 mAh/g, which becomes 528 mAh/g in the second cycle. The composite of graphite-tin with higher capacity compared to pristine graphite is a promising alternative anode material for lithium-ion battery.
