摘要:
通过化学浴沉积技术在碳纳米管(Carbon nanotube,CNT)表面均匀环绕生长氧化镍(Nickel oxide,NiO)纳米片,采用X射线衍射仪和场发射扫描电镜测试方法观察其晶体结构和微观形貌,测试表明:CNT作为核心骨架,NiO纳米片在CNT表面均匀地立体生长。通过循环伏安与恒流充放电测试发现:NiO/CNT复合材料作为锂离子电池负极材料的比容量和循环性能有明显改善,在100 mA/g电流密度下NiO/CNT首次放电比容量1990 mAh/g,比纯NiO的1560 mAh/g提高了276%,循环30次后比容量仍保持在1500 mAh/g,而NiO衰减到285 mAh/g。其比容量和循环性能的改善,是由于CNT提高了复合材料整体的导电性能,NiO纳米片环绕生长在CNT表面上,促进活性材料与电解液的有效接触,增强NiO的电化学活性。
