Highly efficient flexible Li–S full batteries with hollow Ru–RuO2−xnanofibers as robust polysulfide anchoring-catalysts and lithium dendrite inhibitors

The synergy of defective Ru–RuO 2− x heterostructures and N-doped hollow carbon nanofiber conductive fabric, can effectively alleviate polysulfide shuttling and realize uniform dendrite-free Li deposition, affording highly efficient Li–S full batteries.
