High specific surface area porous graphene grids carbon as anode materials for sodium ion batteries

论文摘要

Although great accomplishments of functional material synthesis have been achieved in sodium ion batteries（SIBs）recently,there are still numerous challenges and problems in preparing carbon-based materials with porous architectures and enough lattice distance for Na+insertion.Herein we report a templated strategy to synthesize 3D porous graphene girds（PGGs）consisting of several stacking graphene structure with ultrahigh surface area and hierarchical connected structure by employing Ag nanoparticles（NPs）.The Ag NPs will regenerate for decreasing the experimental cost,also in line with principles of green chemistry and environmentally friendly strategy.The PGGs obtain advanced specific capacity of160 m A h g-1at current density of 50 m A h g-1.Moreover,112 mA h g-1capacity can be gained at 1 A h g-1during 1000 cycles.Due to their porous architecture,ultrahigh surface area and low amorphous graphited structure,PGGs electrode showed the excellent electrochemical performance in high rate capability.
