Effects of cobalt–nickel hydroxides content on electrochemical behaviors of polyacrylonitrile-based activated carbon nanofibers |
| 초록 |
In this paper, the cobalt–nickel (Co-Ni) hydroxides/carbon nanofiber composites with high loading of nickel–cobalt oxides were prepared by a well-known electrospinning method. The composition of the binary oxides in the composite electrodes was controlled easily and accurately in the precursors. The surface morphologies and structural characteristics of activated carbons were observed by SEM and XRD, respectively. The N2 adsorption isotherm characteristics at 77K were confirmed by Brunauer-Emmett-Teller (BET) and Dubinin-Radushkevich (DR) equations. The capacitive properties of the composite electrodes were investigated by cyclic voltammetry and galvanostatic charge–discharge methods. Additionally, the effects of different Co-Ni molar ratios on the capacitive properties of the cobalt–nickel hydroxides/carbon nanofiber composites were investigated. |
