UTILIZATION OF CO-BDC MOF AS ELECTRODE MATERIAL OF A COIN-CELL TYPE ASYMMETRIC SUPERCAPACITOR

Producing electrode materials with high energy density and structural stability is crucial for advanced supercapacitor technologies. In this study, Co-BDC MOF material was synthesized by the solvothermal method and this material was used as an electrode material in an asymmetric supercapacitor device. The structural characterization of the produced Co-BDC MOF material was applied with XRD, FTIR analysis and FE-SEM analysis. The results of these analyses proved the successful production of Co-BDC MOF. Moreover, Co-BDC MOF was used as a material of electrode in the supercapacitor device and its supercapacitive performance was determined by electrochemical tests. According to the electrochemical test results of the supercapacitor device, the areal capacitance values at a scan rate of 5 mV.s-1 were calculated as 68 mF.cm-2. After 5000 cycles, it retained 77.6% of its initial capacitance. At a current density of 0.25 mA.cm-2, the energy and power densities of supercapacitor were determined as 13 µWh.cm-2 and 237 µW.cm-2, respectively. These results show that the Co-BDC MOF has attractive potential for supercapacitor application.
