A high performance flexible planner supercapacitor electrodes were fabricated using poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT) embedded polyvinylpyrrolidone (PVP)/MnCO3 composites under hydrothermal technique. The chemical compositions, surface morphologies, crystalline studies of the consequential composites were examined by carrying out Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, Scanning electron microscopy and X-ray diffraction studies. The XPS summaries of the composites revealed typical peaks of Mn 2p1/2 (653.1 eV), Mn 2p3/2 (641.9 eV), N1s (401.4 eV), and C1s (285.3 eV). The planar designed supercapacitor showed notable areal capacitance of ~48 mFcm-2 and a gravimetric specific capacitance of 360 Fg-1 with good energy density. The supercapacitor demonstrated excellent capacity preservation of 90% subsequently 100,000 charge-discharge cycles. The highly flexible PEDOT/PVP/MnCO3 composite based planar supercapacitor fabricated in this report was initiated to appropriate for application in smart electronic devices and wearable electronics as energy storage system. |
