Two-dimensional NiCo2O4 nanosheet-coated three-dimensional graphene networks for high-rate, long-cycle-life supercapacitors.
We report the synthesis of two-dimensional (2D) NiCo2O4 nanosheet-coated three-dimensional graphene network (3DGN), which is then used as an electrode for high-rate, long-cycle-life supercapacitors. Using the 3DGN and nanoporous nanosheets, an ultrahigh specific capacitance (2173 F g(-1) at 6 A g(-1)), excellent rate capability (954 F g(-1) at 200 A g(-1)) and superior long-term cycling perform...
متن کاملMass production of highly-porous graphene for high-performance supercapacitors
This study reports on a facile and economical method for the scalable synthesis of few-layered graphene sheets by the microwave-assisted functionalization. Herein, single-layered and few-layered graphene sheets were produced by dispersion and exfoliation of functionalized graphite in ethylene glycol. Thermal treatment was used to prepare pure graphene without functional groups, and the pure gra...
متن کاملThree-dimensional skeleton networks of graphene wrapped polyaniline nanofibers: an excellent structure for high-performance flexible solid-state supercapacitors
Thin, robust, lightweight, and flexible supercapacitors (SCs) have aroused growing attentions nowadays due to the rapid development of flexible electronics. Graphene-polyaniline (PANI) hybrids are attractive candidates for high performance SCs. In order to utilize them in real devices, it is necessary to improve the capacitance and the structure stability of PANI. Here we report a hierarchical ...
متن کاملGraphene Foam as a three-dimensional Platform for Myotube Growth.
This study demonstrates the growth and differentiation of C2C12 myoblasts into functional myotubes on 3-dimensional graphene foam bioscaffolds. Specifically, we establish both bare and laminin coated graphene foam as a biocompatible platform for muscle cells and identify that electrical coupling stimulates cell activity. Cell differentiation and functionality is determined by the expression of ...
متن کاملThree-dimensional strutted graphene grown by substrate-free sugar blowing for high-power-density supercapacitors
Three-dimensional graphene architectures in the macroworld can in principle maintain all the extraordinary nanoscale properties of individual graphene flakes. However, current 3D graphene products suffer from poor electrical conductivity, low surface area and insufficient mechanical strength/elasticity; the interconnected self-supported reproducible 3D graphenes remain unavailable. Here we repo...
