| 제목 | Enhanced Electrochemical Performance of Hierarchical MnO2 Nanosheet Array-based Carbon Fiber Paper as Pseudocapacitor Electrode |
| 초록 | In this work, we synthesized hierarchical porous structure of MnO2 nanosheet arrays based on carbon fiber paper (CFP) which can provide three dimensional electron and ion transfer. As-synthesized MnO2/CFP is thoroughly characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Such structure of MnO2/CFP enabled to a good electrical connection each other and elimination of polymeric binders and carbon additives which are generally used in convention electrode preparation. When testing as an electrode of supercapacitor, the MnO2/CFP shows a high specific capacitance (204 F/g), high rate capability (75% retention), and good cycling life (~ 100% retention after 1000 cycles). Keywords: MnO2, Carbon fiber paper, Supercapacitor, Pseudocapacitance, Electrochemical properties. |
