摘要：

Si/C composite was prepared by ball milling and subsequent pyrolysis process using nanosilicon, flake graphite, and phenolic resin as raw materials. The effect of different binders on the performance of Si/C composite was investigated. XRD and FT-IR were used to characterize the structure of the binders, and SEM was used to characterize the morphology of the electrodes. The electrochemical results showed that LA133 had the best performance; the initial charge capacity was 660.4mAhg(-1), with a capacity retention of 92.9% after 50cycles. Compared with PVDF and sodium alginate, better cycling performance was obtained using LA133 as binder of Si/C composite.
