A novel and simple method has been developed to prepare the Cu-Si composite as anode material for lithium-ion batteries. Nanoporous Cu-Si composite with pore sizes of 1~30 nm was prepared by dealloying the melt-spun Al-Cu-Si-Ce ribbons in a 5 wt.% HCl solution. Electrochemical tests revealed that the nanoporous Cu-Si electrodes exhibited highly reversible capacity of 2317 mAhg-1 and retained a capacity of 1030 mAhg-1 over 20 cycles. The excellent electrochemical performance is attributed to the unique porous structure of the Cu-Si composite. Our results demonstrate that this novel composite is a promising anode candidate for high-capacity rechargeable lithium-ion batteries.

We present a new Al-Cu-Mn system to fabricate nanoporous copper ribbons by dealloying. The microstructures of the nanoporous copper ribbons are characterized using X-ray diffraction, scanning electron microscopy and energy dispersive X-ray analysis. The results show that the compositions of the melt-spun Al-Cu-Mn alloys have an important effect on the dealloying process and microstructures of the nanoporous copper ribbons. The melt-spun Cu30Al40Mn30, Cu30Al35Mn35, Cu30Al30Mn40 and Cu30Al25Mn45 (at.%) alloys can completely form a bicontinuous interpenetrating ligament-channel structure. Compared with other alloys, the dealloying of Cu30Al40Mn30 alloys is more difficult. In addition, for Cu30Al35Mn35 and Cu30Al30Mn40 alloys, porous structures are relatively uniform. But for the Cu30Al25Mn45 alloys, porous structure is not uniform, occurring aggregation phenomenon.
