摘要/Abstract

摘要： 采用化学镀方法制备三维多孔铜.以其作为集流体,借助电沉积制备三维多孔Sn-Co合金电极.X-射线衍射(XRD),扫描电镜(SEM)分析表明,以多孔铜为集流体制备的SnCo合金电极主要存在CoSn2相和纯Sn相,为三维多孔结构.充放电结果显示,三维结构SnCo合金电极比平面铜集流体上镀得的SnCo合金电极表现出更优越的充放电性能.前者的首次放电(嵌锂)容量为636.3mAh/g,充电(脱锂)容量为528.7mAh/g,首次库仑效率为83.1%,70周后容量为529.5mAh·g-1,保持率为82.6%.此外,还应用电化学阻抗初步研究了三维Sn-Co合金电极在充放电过程发生的嵌脱锂过程.

Abstract: Three-dimensional porous Cu film was prepared by electroless plating,and used as a current collector for preparation of three-dimensional structured SnCo alloy electrode,which was mainly prepared by an electrodeposition method,and composed of pure Sn and CoSn2 phases. Electrochemical experimental results show that three-dimensional structured SnCo alloy electrode exhibits much better cycleability than planar SnCo alloy electrode,with first discharge capacity and charge capacity of 636. 3 and 528. 7 mAh·g-1,respectively. After 70th cycling,capacity retention is 83. 1% with 529. 5 mAh·g-1. The lithiation process during first discharge was investigated by electrochemical impedance spectroscopy

Key words: porous Cu, lithium ion batteries, SnCo alloy electrode, anode, electrochemical impedance spectroscopy
