| 英文摘要 | Carbonate-based electrolytes demonstrate safe and stable electrochemical performance in lithium-sulfur batteries. however, only a few types of sulfur cathodes with low loadings can be employed and the underlying electrochemical mechanism of lithium-sulfur batteries with carbonate-based electrolytes is not well understood. here, we employ in operando x-ray absorption near edge spectroscopy to shed light on a solid-phase lithium-sulfur reaction mechanism in carbonate electrolyte systems in which sulfur directly transfers to li2s without the formation of linear polysulfides. based on this, we demonstrate the cyclability of conventional cyclo-s 8 based sulfur cathodes in carbonate-based electrolyte across a wide temperature range, from -20 degrees c to 55 degrees c. remarkably, the developed sulfur cathode architecture has high sulfur content (>65 wt%) with an areal loading of 4.0 mg cm(-2). this research demonstrates promising performance of lithium-sulfur pouch cells in a carbonate-based electrolyte, indicating potential application in the future. |
