Abstract：Electroless copper plating on silicon particles was carried out with colloid palladium solution as activation liquid and NaH2PO2×H2O as reducing agent. The optimal coating conditions were obtained through orthogonal experiments. Phase analysis was run by XRD, SEM and TEM, and performance of electrochemistry examined by charging and discharging test. The results show that silicon surface is coated with a layer of dense copper particles. The Si-Cu composite anode of lithium-ion batteries shows good electrochemical performance, the initial discharge specific capacity reaches 1185 mA×h/g, after 30 cycles, the capacity gradually is reduced to 457 mA×h/g and can maintain 350 mA×h/g in the next 30 cycles. Therefore, Si-Cu composite can inhibit the volume effect of Si and improve the cycle performance of the electrode.
