Owing to these excellent qualities as cathode for LSBs, S@u\u2010NCSe delivers outstanding initial capacities up to 1403 mAh g \u22121 at 0.1 C and retains 626 mAh g \u22121 at 5 C with exceptional rate performance. More significantly, a very low capacity decay rate of only 0.016% per cycle is obtained after 2000 cycles at 3 C. Even at high sulfur loading (3.2 mg cm \u22122 ), a reversible capacity of 557 mAh g \u22121 is delivered after 600 cycles at 1 C. Density functional theory calculations further confirm the strong interaction between NCSe and LiPS, and cytotoxicity measurements prove the biocompatibility of NCSe. This work not only demonstrates that transition metal selenides can be promising candidates as sulfur host materials, but also provides a strategy for the rational design and the development of LSBs with long\u2010life and high\u2010rate electrochemical performance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/adfm.201903842 Authors: Chaoqi Zhang, Jordi Jacas Biendicho, Ting Zhang, Ruifeng Du, Junshan Li, Xuhui Yang, Jordi Arbiol, Yingtang Zhou, J.R.
