摘要：

The thin film Sn-Co-Ni alloy electrodes were prepared by electroplating on copper foil as current collector. The structure of the electroplated porous thin film Sn-Co-Ni alloy electrode is investigated by XRD, FE-SEM, and EDAX. The electrochemical performance is analyzed by using a battery cycler at the current rate of 0.1 C to cut-off potentials of 0.01 and 1.20 V vs. Li/Li+ and also cyclic voltammeter. Experimental results illustrate that the initial discharge capacity of the Sn-Co-Ni alloy anode is 717 mAh g(-1). The discharge capacity has been in increasing order between 2nd and 10th cycling and then maintained the stable capacity. It is found that the charge and discharge capacity of thin film Sn-Co-Ni alloy electrode obtained an average reversibility behavior and the better cycle stability. (C) 2011 Elsevier B.V.
