Lithium‐Sulfur Batteries: The Importance of Confined Sulfur Nanodomains and Adjoining Electron Conductive Pathways in Subreaction Regimes of Li‐S Batteries (Adv. Energy Mater. 19/2017)

In article number 1700074, Jan Wook Choi, Kookheon Char, Yung-Eun Sung, and co-workers report an organized nanocomposite to achieve a stable cycling performance. The sulfur cathode contains linear sulfur chains covalently bonded to oleylamine-functionalized reduced graphene oxide. In this electrode structure, confined sulfur nanodomains and adjoining electric conductive pathways synergistically suppress lithium polysulfide dissolution to the electrolyte while facilitating electron transport, leading to exceptional cycling and rate performance.
