Synthesis, Characterization and Fabrication of Ni/NiO Nanoflake Aerogels as Anodes for Asymmetric Supercapacitors |
| 초록 |
In the field of energy storage and conversion, there is a high demand for a device delivering high energy and power density. In search of this device, α-Ni(OH)2 aerogels and the annealed NiO/Ni aerogels were employed to design and fabricate a two-electrode supercapacitor device. Transition metal oxide aerogels are a fascinating class of compounds that have gained a lot of attention in the last decade due to their exceptional and unique properties such as high porosity, high surface area and ultralow density. The physicochemical properties of the as-synthesized aerogels were characterized by XRD, SEM, TEM, BET and XPS studies. The annealed NiO/Ni aerogels show interesting specific capacitance of 1060 F/g with good cycling stability (up to 10000 cycles). The supercapacitor also exhibited an energy density of 32.4 Wh/kg and a power density of 1800 W/kg at a current density of 2 A/g. The practical application of the aerogel was demonstrated by fabricating a two-electrode device. |
