Graphene materials are considered excellent building blocks for high performance applications in electrochemical storage because of the unique structural, mechanical, and electric properties. Meanwhile, the rational combination of graphene building blocks into multi-functional architectures remains as the key challenge. 
At the building block level, graphene layers tend to stack with each other, which cause the loss of specific surface area and degrade its electrochemical performance. Therefore, preventing the stacking of graphene is essential to demonstrate their full potential applications for energy storage. We developed an intrinsic unstacked double-layer templated graphene (DTG) materials grown on mesoporous layered double oxide flakes via template-directed chemical vapor deposition. The DTG is composed of two unstacked graphene layers separated by a large amount of meso-sized protuberances. Meanwhile, a series of graphene-carbon nanotube hybrid materials was also developed to serve as high-performance scaffold in lithium sulfur batteries. Based on graphene building blocks, we are able to assemble flexible architectures to fulfill the requirements in electrodes for lithium sulfur battery, such as high mechanical stability, high electric conductivity in the electrodes. The three-dimensional flexible electrodes based on graphene building blocks present high energy density and high rate capability when serving as sulfur cathode scaffold.
Such graphene-based three-dimensional architectures are expected to be important platform to investigate the stabilized three-dimensional (3D) topological porous systems and demonstrate the potentials of nanocarbons with huge specific surface area, extraordinary thermal and electric conductivity, robust 3D scaffold, as well as tunable surface chemistry for advanced energy storage, environmental protection, nanocomposites, electronic devices, as well as healthcare applications.
