英文摘要	Confining lithium polysulfide intermediates is one of the most effective ways to alleviate the capacity fade of sulfur-cathode materials in lithium-sulfur (Li-S) batteries. To develop long-cycle Li-S batteries, there is an urgent need for material structures with effective polysulfide binding capability and well-defined surface sites; thereby improving cycling stability and allowing study of molecular-level interactions. This challenge was addressed by introducing an organometallic molecular compound, ferrocene, as a new polysulfide-confining agent. With ferrocene molecules covalently anchored on graphene oxide, sulfur electrode materials with capacity decay as low as 0.014% per cycle were realized, among the best of cycling stabilities reported to date. With combined spectroscopic studies and theoretical calculations, it was determined that effective polysulfide binding originates from favorable cation-p interactions between Li+ of lithium polysulfides and the negatively charged cyclopentadienyl ligands of ferrocene.; Yale University; China Scholarship Council (CSC); U.S. Department of Energy Office of Science, Office of Basic Energy Sciences [DE-FG02-07ER15909]; Argonne-Northwestern Solar Energy Research (ANSER) Center, an Energy Frontier Research Center - U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences [DE-PS02-08ER15944]; SCI(E); PubMed; ARTICLE; victor.batista@yale.edu; hhzhou@pku.edu.cn; hailiang.wang@yale.edu; 47; 14818-14822; 55
