为了进一步增大锂离子电池的能量密度与功率密度， Si基负极材料已经得到了广泛而深入地研究。Si材料具有很高的比容量，低的电压平台，环境友好且储量丰富。然而，Si材料在充放电过程中会发生巨大的体积变化和形成不稳定的SEI膜，限制了Si基负极材料在锂离子电池中的实际应用。最近，针对Si材料作为锂电池负极材料上的缺陷而进行了大量的研究且取得了比较好的研究结果。

In order to further increase the energy density and power density of lithium-ion batteries, silicon-based anode materials have got the extensive and in-depth research.Silicon material has the very high specific capacity,low voltage platform,environment friendly and abundant.However,silicon anode will experience a serious volume change and form a unstable solid-electrolyte interphase ( SEI ) during charging and discharging,limiting its practical application in lithium ion battery.Recently,much research work has been made based on the flaws of silicon anode and achieving good results.
