However, there are still some challenges for the commercialization of LSBs, such as the sluggish redox reaction kinetics and the shuttle effect of lithium polysulfides (LiPS). Here a 2D layered organic material, C 2 N, loaded with atomically dispersed iron as an effective sulfur host in LSBs is reported. X\u2010ray absorption fine spectroscopy and density functional theory calculations prove the structure of the atomically dispersed Fe\/C 2 N catalyst. As a result, Fe\/C 2 N\u2010based cathodes demonstrate significantly improved rate performance and long\u2010term cycling stability. Fe\/C 2 N\u2010based cathodes display initial capacities up to 1540 mAh g \u22121 at 0.1 C and 678.7 mAh g \u22121 at 5 C, while retaining 496.5 mAh g \u22121 after 2600 cycles at 3 C with a decay rate as low as 0.013% per cycle. Even at a high sulfur loading of 3 mg cm \u22122 , they deliver remarkable specific capacity retention of 587 mAh g \u22121 after 500 cycles at 1 C. This work provides a rational structural design strategy for the development of high\u2010performance cathodes based on atomically dispersed catalysts for LSBs.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/aenm.202003507 Authors: Zhifu Liang, Dawei Yang, Pengyi Tang, Chaoqi Zhang, Jordi Jacas Biendicho, Yi Zhang, Jordi Llorca, Xiang Wang, Junshan Li, Marc Heggen, J\u00e9r\u00e9my David, Rafal E.
