dc.description.abstract | The nano crystalline NiCo2O4 blended with MWCNT with various proportionate (5%, 10% and 15%) was synthesized via temperature dependent Co-prepation techniques with a perspective to investigate dielectric and electrical response for improvement its supercapacitor applications. The X-ray diffractometer, FESEM and TEM techniques were used to identify its phase purity, surface morphology, elemental composition and homogeneous grain growth in nm range for various compositions. The FTIR spectra exhibit the suppression of the metal oxide (Ni-O, Co-O) vibrations with the incorporation of MWCNT. The dielectric constant and loss was increased with the evolution of MWCNT percentages and the outmost value of dielectric constant was observed 8x104 at room temperature. The i-v characteristics spectacles on improved electrical current from μA to mA with inclusion of MWCNT. The electrochemical properties indicates that the specific capacitance of NiCo2O4/MWCNTs was increased 12.5% and about 97.9% of the capacitance retained after 3000 charge-discharge cycles as compared to pure NiCo2O4. The good electrochemical performances proposed that these NiCo2O4/MWCNTs composites could be promising materials for energy and ecologically related applications. | en_US |
