| 제목 | Nickel-tungsten oxides anchored on hollow carbonnanosphere for supercapacitor application. |
| 초록 | The demand for energy storage is increasing as a result of the depletion of energy resources. With the propose of improving the energy storage, supercapacitor isone of the applications for future storage applications. In this work, wesynthesized N-doped hollow carbon sphere (NHCS) encircled by the nickeltungstate nanoparticles (NHCS/NiWO 4 ). N-doped hollow carbon spheres (NHCS) possess hollow morphology, rough surface, large surface area, and shortelectron transport pathway occurs during the charge and discharge; and the electrical conductivity and stability of the composites were increased due to the presence of nitrogen in hollow carbon sphere. Meanwhile, the higher electrically conductive NiWO4 nanoparticles provide numerous active sites which results in the improvement of specific capacitance. The combination of two materials generates a high performance cathode electrodes in supercapacitor. |
