【摘要】 通过氧化铝模板辅助生长方法制备了用于锂离子电池的锡镍合金纳米棒电极。通过扫描电子显微镜,能谱色散X射线分析对锡镍合金纳米棒电极进行了形貌和成份表征。扫描电子显微镜观察显示铜集流体表面均匀分布着锡镍合金纳米棒阵列。通过恒流充放电方法对锡镍合金纳米棒电极的电化学性能进行了初步表征,结果表明锡镍合金纳米棒电极具有良好的容量保持率。更多还原

【Abstract】 Sn-Ni nanorod electrodes for lithium ion rechargeable batteries are fabricated by an anodic aluminum oxide template-assisted growth method.The structural and morphological characteristics of the electrode were examined using scanning electron microscopy.Scanning electron microscopic observation reveals that the copper substrate is covered with uniformly distributed Sn-Ni alloy nanorods.The electrochemical properties of the Sn-Ni alloy nanorod electrodes are studied by galvanostatic cycling. The results show the Sn-Ni alloy nanorod electrode delivered excellent capacity retention.更多还原
