摘要：

A lithium-polysulfide cell with superior stability is reported with N,O-codoped carbon hollow fiber (NCHF) sheets as a current collector. Due to the highly effective chemisorption and physical adsorption of lithium polysulfides on doped NCHF and a uniform Li2S precipitation during cycling, the Li2S6-impregnated NCHF electrodes exhibit high sulfur utilization and superior cycling stability even with a high areal sulfur loading of 6.2 mg cm(-2).
