Electrochemical behaviors of sulfur-containing electrodes derived from zeolitic imidazolate framework for rechargeable lithium battery |
| 초록 |
Porous carbon materials prepared by directly carbonization of metal organic frameworks (MOFs) have been attracted due to higher specific surface area and good electrical conductivity. These are the main reasons why MOFs were investigated and applied for catalysts, gas storage and energy storage system. Zeolitic imidazolate frameworks (ZIFs) are subclass of MOF and cobalt-based ZIF was synthesized through simple solvothermal reactions in this study. The additional thermal treatment was proceeded at different temperature for 3 hours. The morphology of composites was examined by Field Emission Scanning Electron Microscopy and Fourier Transform Infra-Red spectroscopy. By Galvanostatic charge-discharge tests and cyclic voltammetry tests were conducted to verify electrochemical performance. The ZIFs-sulfur cathode treated at 900 ℃ shows 1260 mAhg-1 of initial specific capacity and good cycle performance in this study. |
