Abstract Here, monoclinic CePO4 nanorods is synthesized and firstly evaluated as a novel anode of Li-ions batteries (LIBs). The results illustrate that the obtained CePO4 nanorods can be inserted up to 7.4Li+ per formula unit in the first discharge and 2.8Li+ can be extracted reversibly in the range of 0.01 ~ 3.0 V. A reversible capacity of 335/301 mAh g−1 is achieved after 100/500 cycles at a current density of 0.5/1.0 mA cm−2, respectively. The capacitive contribution to the total charge storage is also analyzed. The results are important in further clarifying CePO4 role in LIBs.

单斜CePO4纳米棒电化学存储性能的合成与研究

摘要 这里合成了单斜 CePO4 纳米棒，并首次将其作为锂离子电池 (LIBs) 的新型负极进行评估。结果表明，所获得的CePO4纳米棒在第一次放电时每配方单元最多可以插入7.4Li+，并且可以在0.01~3.0 V范围内可逆地提取2.8Li+。可逆容量为335/301 mAh g-1分别以 0.5/1.0 mA cm-2 的电流密度在 100/500 次循环后实现。还分析了对总电荷存储的电容贡献。该结果对于进一步阐明 CePO4 在 LIB 中的作用很重要。
