We report a rGO-HCS composite to encapsulate sulfur with high sulfur contents from 70 to 90wt% as sulfur cathode. The rGO-HCS/S composite loading 90wt% sulfur delivers a high discharge capacity of 860 mAhg-1 (corresponding to1300 Wh kg-1 based on mass of the whole cathode) and obtains a high capacity retention of 77% after 78 cycles at a high sulfur areal density of 3 mg cm-2.The results indicate the great potential of the rGO-HCS nanostructure as promising sulfur host loading high content of sulfur with high gravimetric and volumetric energy density. | Highly sensitive simultaneous determination of cadmium (II), lead (II), copper (II), and mercury (II) ions on N-doped graphene modified electrode Original Research Article Journal of Electroanalytical Chemistry, Available online 30 November 2015, Pages Huakun Xing, Jingkun Xu, Xiaofei Zhu, Xuemin Duan, Limin Lu, Wenmin Wang, Youshan Zhang, Taotao Yang | |
