Sulfur–Graphene Nanostructured Cathodes via
Although much progress has been made to develop highperformance lithium–sulfur batteries (LSBs), the reported physical or chemical routes to sulfur cathode materials are often multistep/complex and even involve environmentally hazardous reagents, and hence are infeasible for mass production. Here, we report a simple ballmilling technique to combine both the physical and chemical routes
