摘要：

Eight new strategically designed fluoroether sulfone solvents have been synthesized through different synthetic pathways for potential applications in lithium-sulfur battery electrolytes. The structures of these compounds have been confirmed by H-1-NMR, C-13-NMR and elemental analysis. Several 1,2-dimethoxyethane (DME)-based electrolyte formulations have been prepared with these solvents to derive an electrolyte with good ionic conductivity (> 5 mS cm(-1) at 25 degrees C). The viscosity of these new additives has also been determined as it is directly related to the ionic conductivity. Three of these solvents that contain a trifluoromethyl group displayed acceptable ionic conductivity.
