Electrochemical Performance of Hollow Silicon/Carbon Anode Materials for Lithium Ion Battery

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.

Carbon Anodes

Lithium-ion batteries are widely used in various industries, such as portable electronic devices, mobile phones, new energy car batteries, etc., and show great potential for more demanding applications like electric vehicles. Among advanced anode materials applied to lithium-ion batteries, silicon–carbon anodes have been explored extensively due to their high capacity, good operation potential, environmental friendliness and high abundance. Silicon–carbon anodes have demonstrated great potential as an anode material for lithium-ion batteries because they have perfectly improved the problems that existed in silicon anodes, such as the particle pulverization, shedding and failures of electrochemical performance during lithiation and delithiation. However, there are still some problems, such as low first discharge efficiency, poor conductivity and poor cycling performance, which need to be improved. This paper mainly presents some methods for solving the existing problems of silicon–carbon anode materials through different perspectives.
