Silicon (Si) is considered to be one of the alternative anode candidates for lithium-ion batteries due to the high theoretical capacity. Enhancing the columbic efficiency, cycle stability, alleviating the pulverization and decreasing the manufacturing cost are the major challenges that procrastinate the commercialization of Si anode. Inspirited by spiderweb structure, the Si nanoparticles (SiNPs)...
A simple yet efficient one-step route is reported to prepare a three-dimensional interconnected thin-layer carbon network consisting of graphene sheets sandwiched by a porous carbon layer (PCG). Our route relies on the direct pyrolysis of ethylene diamine tetraacetic acid tripotassium salt (EDTA-3K) in the presence of polyelectrolyte-functionalized graphene oxide (GO) at 750 °C. The decomposition...
The newly emerging graphene/hexagonal boron nitride (h-BN) van der Waals heterostructures has attracted much research interest due to its new properties and functions for practical applications in nanodevices. In this work, molecular dynamics simulations are performed to study the interfacial thermal resistance (ITR) of a graphene/h-BN bilayer system as well as its one-dimensional counterpart, a concentric...
