摘要

通过水热法制备了一维结构的硫化铋(Bi₂S₃)纳米棒和Bi₂S₃纳米带材料,利用原位透射电镜研究了两者一维结构的原位锂化过程,并组装成电池测试了它们的电化学性能。结果表明:Bi₂S₃纳米带在锂化过程中表现在优于Bi₂S₃纳米棒的结构稳定性,从而在电化学测试中表现出更好的循环稳定性。

Abstract

One-dimensional bismuth sulfide (Bi₂S₃) nanorods and Bi₂S₃ nanobelts were prepared through a hydrothermal method.The in-situ lithiation processes of both one-dimensional structures were studied using transmission electron microscopy.They were assembled into batteries,and their electrochemical performances were tested.The results showed that Bi₂S₃ nanobelts exhibited better structural stability during the lithiation process than Bi₂S₃ nanorods,resulting in superior cyclic stability in electrochemical testing.
