摘要:
为提高锂离子电池负极材料钛酸锂的倍率性能,本文采用软模板法制备具有空心结构的钛酸锂(Li4Ti5O12),并研究了其电化学储锂性能。通过调节模板剂十二胺的添加量,控制形成空心球形结构的TiO2前驱体,再利用化学锂化,制得继承空心球形结构的Li4Ti5O12。XRD、SEM分析表明所制备的Li4Ti5O12为纯相,且其形貌均匀,空心结构明显。对其进行电化学性能测试表明:该空心球状Li4Ti5O12电极材料具有优良的电化学性能,其首周容量为170 mAh/g,循环100周后容量仍能保持155 mAh/g以上,并且表现出优异的倍率性能,在5、20、80 C下的放电容量分别为135、115、100 mAh/g。
