Ni 3 S 2 anchored to N/S co-doped reduced graphene oxide with highly pleated structure as a sulfur host for lithium–sulfur batteries

As a sulfur host for the lithium–sulfur battery, Ni 3 S 2 anchored to N/S co-doped RGO with a highly pleated structure has demonstrated the strong capture of polysulfides, exhibiting high reversible capacity and cycling stability.
