摘要：

The cooperative effects between the PANI (polyaniline)/nano-NiO (nano nickel oxide) composite electrode material and redox electrolytes (potassium iodide, KI) for supercapacitor applications was firstly discussed in this article, providing a novel method to prepare nano-NiO by using beta-cyelodextrin (beta-CD) as the template agent. The experimental results revealed that the composite electrode processed a high specific capacitance (2122.75 F.g(-1) at 0.1 A.g(-1) in 0.05 M KI electrolyte solution), superior energy density (64.05 Wh.kg(-1) at 0.2 A.g(-1) in the two-electrode system) and excellent cycle performance (86% capacitance retention after 1000 cycles at 1.5 A.g(-1)). All those ultra-high electrical performances owe to the KI active material in the electrolyte and the PANI coated nano-NiO structure.
