Silicon/Carbon Anodes with One-Dimensional Pore Structure for Lithium-Ion Batteries

Abstract

In this report, we Si/C composite with porous and yolk-shell structure, carbon coated mesoporous Fe2O3, C/CuO and S/C composites using aerosol pyrolysis, electrospray and CVD techniques. The electrochemical peroformances of these materials were tested, and the mechanism for long cycling stability and high rate capability of these materials were investigated. The findings were published in top journals. The objectives of this project in the year-two are to develop porous Si/C and C/S composite electrodes for high performance lithium ion batteries and to investigate the mechanism how the porous carbon matrix enhances the cycling stability of Si and S electrodes.
