Abstract
This study focused on the effects of sulfur doping on the properties of thermally reduced graphene oxide nanoribbons (rGONRs) and their usage as anodes in Na-ion batteries. Sulfur-doped rGONRs (S-rGONRs) were fabricated by unzipping carbon nanotubes and thermally treating them with elemental sulfur. The prepared S-rGONRs showed a higher reversible capacity of 395 mAh gâ1 than rGONRs, which have a capacity of 257 mAh gâ1. In addition, they exhibited high reversibility, a high rate capability of 20 A gâ1, and stable cyclic performance for over 4000 cycles.
