Lithium-sulfur batteries (LSBs) are currently considered as a promising candidate for nextgeneration energy storage technologies. However, their practical application is hindered by a critical issue of polysulfide-shuttle. Herein, we present a metal organic framework (MOF) -derived solid electrolyte to address it. The MOF solid electrolyte is developed based on a UIO (Universitetet i Oslo) structure. By grafting a lithium sulfonate (-SO 3 Li) group to the UIO ligand, both the ionic conductivity and the polysulfide-suppression capability of the resulting UIOSLi solid electrolyte are greatly improved. After integrating a Li-based ionic liquid (Li-IL), LiTFSI in 1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM [TFSI]), the resulting Li-IL/UIOSLi solid electrolyte exhibits an ionic conductivity of 3.3 × 10 -4 S cm -1 at room temperature.

Lithium-sulfur cells with the Li-IL/UIOSLi solid electrolyte and a Li 2 S 6 catholyte show stable cycling performance that preserve 84% of the initial capacity after 250 cycles with a capacity-fade rate of 0.06% per cycle.
