      摘要:
      為提高鋰離子電池負極材料鈦酸鋰的倍率性能365英超体育投注,本文采用軟模板法制備具有空心結構的鈦酸鋰(Li4Ti5O12),并研究了其電化學儲鋰性能365英超体育投注。通過調節模板劑十二胺的添加量,控制形成空心球形結構的TiO2前驅體365英超体育投注,再利用化學鋰化,制得繼承空心球形結構的Li4Ti5O12。XRD365英超体育投注、SEM分析表明所制備的Li4Ti5O12為純相,且其形貌均勻,空心結構明顯。對其進行電化學性能測試表明:該空心球狀Li4Ti5O12電極材料具有優良的電化學性能,其首周容量為170 mAh/g,循環100周后容量仍能保持155 mAh/g以上,并且表現出優異的倍率性能365英超体育投注,在5、20、80 C下的放電容量分別為135365英超体育投注、115、100 mAh/g。
