Abstract

Nano-sized Cu-Sn alloy powders were prepared by reductive precipitation method combining with the aging treatment in constant temperature water bath at 80 °C. The microstructure, morphology and electrochemical property of synthesized Cu-Sn alloy powders were evaluated by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and galvanostatical cycling tests. The results indicated that the aged sample had uniform phase components, integrated particles, loose network-like structures and excellent electrochemical performance. When used as negative electrodes for lithium-ion batteries, the aged Cu₆Sn₄ and Cu₆Sn₅ samples delivered reversible capacities of about 340 and 370 mAh g^-1 up to 20 cycles, respectively.
