논문 초록 (Abstract)
Three-dimensional porous nickel foam was used as a current collector to prepare a Co-Ni oxide/Ni foam electrode for a supercapacitor. The synthesized Co-Ni oxide was proven to consist of mixed oxide phas es of Co3O4 and NiO. The Co-Ni oxide/Ni foam electrode prepared was characterized by morphological observation, crystalline prope rty analysis, cyclic voltammetry, and impedance spectroscopy. Cyc lic voltammetry for the electrode showed high specific capacitanc es, such as 936 F g(-1) at 5 mV s(-1) and 566 F g(-1) at 200 mV s(-1), and a comparatively good cycle performance. These improved results were mainly due to the dimensional stability of the nickel foam a nd its high electrical contact between the electrode material and the cu rrent collector substrate.
