1. Introduction Lithium-sulfur (Li-S) batteries have garnered intensive research interest for advanced energy storage systems owing to the high theoretical gravimetric (E g) and volumetric (E v) energy densities (2600 Wh kg −1 and 2800 Wh L − 1), together with high abundance and environment amity of sulfur [1, 2].
Here, we report a novel electrolyte with relatively low density (1.16 g cm −3 ), low viscosity (1.84 mPa s), and high ionic conductivity, which significantly promotes energy density and cyclability of Li-S batteries under practical conditions.
