摘要:
为了改善二硫化钼(MoS-2)材料作为锂离子电池负极材料的电化学性能,对其进行复合改性,通过二氧化硅和碳前驱体在碳纳米管上的连续沉积,结合碳化、刻蚀和水热法合成二硫化铜@碳纳米管中管(MoS-2@CTTs)复合材料。利用X 射线衍射仪(XRD)、扫描电子显微镜(SEM)和透射式电子显微镜(TEM)分析MoS-2@CTTs复合材料的物相组成及微观形貌;通过恒流充放电测试、倍率性能测试和循环伏安测试研究该材料的电化学性能。结果表明:在150 mA/g的电流密度时,该材料首次放电比容量达到1057 mAh/g;经过175次循环后,其放电容量为856 mAh/g,容量保持率为81%。这说明制备所得复合材料具有较高的比容量和优异的循环性能。
