摘要:

层状结构的硫化铋(Bi2S3)是一种高性能的能源材料,在电化学催化和储锂方面具有潜在的应用前景。然而,由于本身晶格、电子结构和电学性能的限制,硫化铋的储锂性能还远不能满足实用的需求。倪江锋通过一系列的结构设计与表面修饰,近期在提高硫化铋的储锂性能方面已取得了一些进展【Nano Res. 7,2014,765 (IF 6.963);J. Mater. Chem. A 2,2014,13854(IF6.626)】。最近,倪江锋与高立军、郑洪河、晏成林和李亮教授合作,发展了一种制备具有优异倍率性能和稳定循环寿命的硫化铋复合电极材料技术,并揭示了其改性机理。这项工作在线发表于AdvancedEnergy Materials上。

A strongly coupled Bi2S3@CNThybridwas fabricated and exhibited a stable Li-storage capacity,retaining 405mAh g?1 over 100 cycles at a rate of 1A g?1.More importantly, the hybrid demonstrated robust rate capability, delivering 429 and 376 mAh g?1 at high ratesof 2 and 5 A g?1, thereby suggesting their great potential foradvanced rechargeable battery application.
