A team of researchers from institutions in China and the US report the design of a negatively charged graphene composite separator for the effective suppression of the polysulfide shuttling effect in Li-sulfur batteries. Therefore, despite extensive efforts, the improvement to date remains rather unsatisfactory, especially in energy density.
