• 多壁碳纳米管对SiO电极电化学性能的影响

  来源： 《无机材料学报2008年第3期》——刘素琴 赵薇 黄可龙

  多壁碳纳米管对SiO电极电化学性能的影响 刘素琴1,赵薇1,黄可龙1 (1.中南大学化学,化工学院,长沙,410083) 摘要:以多壁碳纳米管(MWNTs)作负极材料导电剂制备了SiO/MWNTs复合电极.采用恒流充放电测试对比考察了不同含量及类型的导电剂对SiO电极电化学性能的影响.乙炔黑(AB)的SiO电极首次可逆比容量仅为582.3mAh·g-1>而20%MWNTs的电极比容量高达1463.9mAh·g-1>,且SiO的循环性能得到显著改善.SEM,EIS测试结果表明: 多次循环后SiO/MWNTs电极仍能较好地保持活性颗粒的导电网络,而脆性乙炔黑所形成的桥连作用遭到破坏,导致活性颗粒间的接触电阻增大. 关键词:多壁碳纳米管; SiO; 恒流充放电; 电化学性能; [全文内容正在添加中] ......
