CoNb2O6 nanoparticles anchored on 3D graphene as an advanced electrode material for high-power Lithium-Ion capacitors

摘要：

In recent years,bimetallic Niobium-based oxides with special crystal structure have attracted considerable attention of scholars successfully,due to its excellent lithium storage capacity.1,2 In this work,CoNb2O6 nanoparticles anchored on graphene sheets were synthesized through a two-stage hydrothermal method.The composite was characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM) and X-ray photoelectron spectroscopy(XPS),and the results suggest that the CoNb2O6 with a particle size of～30 nm were distributed on graphene sheets evenly.
