铋纳米材料的电化学制备及储锂性能研究

Fabrication of Bi Nanoparticles through Electrochemical Method and Investigation on Its Lithium Storage Property

与传统方法相比,电化学合成纳米材料具有低成本、高效率、绿色环保的优势,当今在科学研究及工业应用中颇受重视。本文以金属铋为前驱体采用便捷、绿色、高效的电化学阴极极化法合成了铋纳米材料,并探索了其在锂离子电池负极材料中的应用。电化学测试说明其可逆比容量达到359.7 mAh/g,然而该电极材料循环性能较差,与之匹配的电解液或粘结剂需进一步优化。

Electrochemical methods are usually performed in mild conditions, which are more convenient and controllable. In this paper, we report a simple,green, and efficient electrochemically cathodic polarization method to synthesize Bi nanomaterials. The as-fabricated Bi nanoparticles used as anode materials for lithium ion battery show a high reversible specific capacity of 359.7 mAh/g.
