1,1,2,2-tetrafluoroethyl 2,2,2-trifluoroethyl ether (TFTFE) was used as a support solvent of solvate ionic liquid (SIL) for lithium-sulfur battery. The fluorinated ether improves the cell performance remarkably.

The suitability of some different kinds of liquid electrolytes with a 1M solution of LiCF3SO3 was evaluated for discharging capacity and cycle performance of Li/S cells at room temperature. The liquid electrolyte component was found to have a profound influence on the discharging capacity and cycle property. The lithium–sulfur battery based on the alcohol-ether binary electrolyte shows two discernible voltage plateaus at around 2.4 and 2.1 V, which correspond to the formation of soluble polysulfides and of solid reduction products, respectively. However, the liquid electrolyte based on carbonate electrolyte shows a bad compatibility with sulfur cathode. The lithium sulfur battery can not deliver acceptable discharging capacity and cycle performances.

Adding Li2S8 as additive in liquid electrolyte (LE) for lithium-sulfur battery (LSB) is one of the most effective strategies which not only suppresses the shuffle effect of lithium polysulfide (LPS) through concentration difference but also maintains the excellent properties of ether-based electrolyte. However, previous researches on this strategy mostly focus on low-concentration Li2S8 additive (no more than 0.2 mol/L), which cannot provide comprehensive understanding of the special role of Li2S8. In this study, high-concentration Li2S8 is selected as the LE additive which is demonstrated inducing two marvelous reconstruction effects that have not been reported both for the cathode and solid electrolyte interphase (SEI). Through these two effects, the cathode and SEI are reconstructed to form denser and more stable structures, ensuring the battery to possess much higher discharge specific capacity and excellent cycle stability, with a Coulombic efficiency (CE) fade of only 0.091% per cycle. This exploration of Li2S8 additive helps to better understand the role of electrolyte additive and how the concentration of it influences the whole battery system.
