中文摘要	Nanometer particles of Cu-Sn alloy, a kind of lithium storage material, with amorphous structures were successfully prepared by a reverse microemulsion technique. Because the electrode pulverization problem can be relieved by its small particle size, nanometer Cu-Sn alloy anode has a good cycle performance. However, a great irreversible capacity was caused by the formation of a SEI layer on the surface of nanometer alloy and the contact resistance between nanometer particles resulted in the poor electric conductivity. It is proved by experiments that the match of particle size and conductive agent content has a great impact on the electrochemical performance of the nanometer Cu-Sn alloy anode. When the conductive agent content increased to 40%, the nanometer Cu-Sn alloy with particle size of 50-60 nm presented the best performance.
