Synergistic Effect of Dual-Functional Groups in MOF-Modified Separators for Efficient Lithium-Ion Transport and Polysulfide Management of Lithium-Sulfur Batteries.

ABSTRACT: Lithium-sulfur batteries (LSBs) have been regarded as an attractive candidate for future energy storage systems owing to their exceptionally high energy density. However, the further application of LSBs is faced with critical challenges such as the intrinsic insulation of sulfur and the shuttle effect of soluble lithium polysulfides (LiPS). To overcome these problems, a dual functional metal-organic framework (UIO-66-NH₂-HSO₃) modified separator is proposed, strategically implemented to examine the dual functionality in anchoring LiPS and facilitating Li⁺ transport. Theoretical calculations indicated that the Li⁺ diffusion kinetics and LiPS adsorption ability are synergistically boosted by the dual-functional groups in the framework. The -HSO
