제목 Carbide-Derived Carbon Composite Cathode for Li-S Rechargeable Battery
초록 The various energy-storage technologies, lithium-sulfur batteries have been intensively investigated as one of the most promising systems for the next generation high-energy rechargeable lithium batteries because of their high theoretical specific capacity (1680 mA h g-1) and energy density (2500 Wh kg-1). However, although this system has been gaining attention, it has not been commercialized because of remaining unsolved problems, such as the inherent poor electrical conductivity of sulfur, the shuttle effect of higher-order polysulfides during charging, and the rapid decrease in capacity during cycling. In this study, we prepared a sulfur-coated carbide-derived carbon composite using impregnation methods and investigated the electrochemical properties and capacity through those mythologies.
