英文摘要	In this work, the RGO-modified CoWO4 nanoparticles are synthesized by a feasible hydrothermal approach and studied as the high-performance sodium-ion storage materials. RGO can effectively improve overall electrical conductivity and maintain the stability of the composite structure. The composites exhibit a stabilized reversible capacity of 160mAhg(-1) at the current density of 100mAg(-1) after 100cycles when tested as the anode materials of sodium-ion batteries (SIBs). The sodium-ion capacitors (SICs) were assembled using CoWO4/RGO nanocomposites as the negative electrode materials and the active carbon (AC) as the positive electrode materials. It could deliver a capacitance about 31Fg(-1) at the current density of 100mAg(-1) and display a specific energy of 87.2Whkg(-1) at the power density of 224.6Wkg(-1). The outstanding electrochemical properties and high energy density of CoWO4/RGO anode materials indicate the huge potential for its application to sodium-ion storage devices.
