摘要：

CoWO4 is predicted to be a very promising electrode material for supercapacitors. In this study, a novel flowerlike morphology of CoWO4 fabricated by a hydrothermal method is presented for the first time. The prepared CoWO4 have been thoroughly characterized by scanning electron microscopy and X-ray diffraction. The special CoWO4 nanostructure exhibits noticeable specific capacitance of 156 F.g(-1) at 0.5 A.g(-1) and shows outstanding rate capability (85.2% capacitance retention at 10 A.g(-1)). The proposed feasible route is expected to be applied prospectively and widely in preparing CoWO4 pseudocapacitive material, which owns great application value in supercapacitors.
