Synergistic effect of multi-metallic and dual-functional groups of a MOF@rGO layer for the catalytic transfer and shuttle inhibition of lithium–sulfur batteries

Abstract

We propose a novel multi-functional MOF@rGO layer which is assembled with dual-function groups, multi-metallic doping, and a highly conductive graphene substrate for the modification of lithium sulfur battery separators. The MOF@rGO layer shows a synergistic effect of catalytic transfer and shuttle effect inhibition of lithium polysulfides, significantly increasing the electrochemical performance.
