"iron exposes more active selenium edge sites in MoSe2, which can selectively adsorb more lithium polysulfides (LiPSs) to minimize the shuttle effect. Moreover, the conductive feature of rGO improves the cell's electrical conductivity and promotes the adsorption of polysulfides via chemical bonding with the functional group of rGO. Therefore, using the Fe-MoSe2@rGO nanohybrid as a functional plane offers the advantages of high conductivity and effective LiPS adsorption"
