Selenium in nitrogen-doped microporous carbon spheres for high-performance lithium–selenium batteries
Yong JiangXiaojian MaJinkui FengShenglin Xiong
Abstract
An integrated composite with confined selenium within nitrogen-doped microporous carbon spheres as a new cathode material can realise the direct transformation between Se atoms and Li2Se in the cycling process, resulting in unprecedented electrochemical performance based on reversible capacity, cycling stability, and rate capability.
