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.
