Conductive porous vanadium nitride/graphene composite as chemical anchor of polysulfides for lithium-sulfur batteries

Lithium sulfur batteries are a promising next generation storage technology. Their performance, however, is subject to the parasitic shuttle effect. Here the authors report a cathode material comprising porous vanadium nitride nanoribbon and graphene to provide anchoring for polysulfides.
