Graphene quantum dots (GQDs) decorated sulfur–carbon hierarchical structure serve as a high sulfur/sulfide utilization in Li–S battery. The oxygen rich functionalities of the GQDs induced structural integrity of the sulfur–carbon electrode composite. This hierarchical structure enables fast charge transfer, minimizes the loss of soluble polysulfides and completes reaction of sulfur/sulfide.
