Abstrak

In quest for cost-affordable but high performing supercapacitor (SC), we explored fabrication of electrode material of copper oxide (CuO) nanostructures using simple solution-based synthesis procedure and different surfactants. Here, we report the influence of the surfactants on the morphological and structural evolutions as well as energy-storage capacity of the CuO. As an SC electrode material, CuO exhibits considerably high specific capacity (51 mAhg−1 @ 1Ag−1), good rate performance (31 mAhg−1 @ 10Ag−1) and better cyclic stability. In addition, it has low charge transfer resistance (1.6 Ω), which is very important when performing charge–discharge at high current rates. These results are highlighting the way for its use in design of advanced CuO-based supercapacitor devices. Keywords: Copper oxide, Neutral electrolyte, Surfactant, Supercapacitor
