Abstract
采用液相法制备铜纳米棒阵列,并用作锂离子电池负极集流体,通过电沉积制备Sn-CO-zn纳米棒阵列合金电极。合金电极主要是由CO Sn、CO Sn2和单质zn组成的混晶。以1 C在0.02~1.50 V循环,合金电极首次循环的放电比容量为813.8 M AH/g,库仑效率为87.5%,第50次循环的放电比容量为467.0 M AH/g。电极活性材料多相结构及纳米阵列间隙,可缓解嵌锂过程中的体积膨胀。
 
Copper nanorods array was prepared by liquid phase reaction and used as anode current collector material for Li-ion battery.Sn-Co-Zn nanorods array alloy electrode was prepared by electrodeposition.The alloy electrode was the mixed crystal mainly composed of CoSn,CoSn2 and Zn.When cycled in 0.02 ~ 1.50 V with 1 C,the specific discharge capacity of alloy electrode in initial cycle was 813.8 m Ah / g,the columbic efficiency was 87.5%,the specific discharge capacity in 50 th cycle was 467.0 m Ah / g.The multi-phase structure of electrode material and the nanorods array could alleviate the volume expansion during lithium intercalation.
