Template growth of porous graphene microspheres on layered double oxide catalysts and their applications in lithium–sulfur batteries

The wise integration of individual two-dimensional graphene nanosheets into three-dimensional (3D) macroscopic architectures is essential for full exploration of their potential applications in electrochemical energy storage. Graphene microspheres (GMSs) with hierarchical porous architectures and high 3D electrical conductivities are highly expected to be the host carbon to accommodate sulfur cathode for lithium–sulfur batteries. Herein we...
