TLDR
Both the physical and chemical properties of the as-prepared separator are beneficial to alleviating the shuttle effect and enhancing the rate capability, and the electrochemical performance of the battery with a MOF-modified separator was significantly improved.Abstract:
Although there are plenty of merits for lithium-sulfur (Li-S) batteries, their undesired shuttle effect and insulated nature are hindering the practical applications. Here, a conductive metal-organic framework (MOF)-modified separator has been designed and fabricated through a facile filtration method to address the issues. Specifically, its intrinsic microporous structure, hydrophilic polar property, and conductive feature could make it easy to contact with and trap polysulfides and boost the kinetics of electrochemical reactions. Both the physical and chemical properties of the as-prepared separator are beneficial to alleviating the shuttle effect and enhancing the rate capability. Accordingly, the electrochemical performance of the battery with a MOF-modified separator was significantly improved.read more
