Carbon based ternary composite of spinel with PANI as excellent electrode material for supercapacitor application

초록

Spinel oxides are desirable material due to their high specific capacitance (Cs) for supercapacitors (SC). However, because of their small surface area, the spinel materials exhibit insufficient conducting and cycle stability. To resolve these drawbacks the carbon and polymer-based material like rGO and PANI are utilized which rises number of sites and surface area. In this work, CuMn2O4/rGO/PANI nanocomposite was synthesized using a straightforward hydrothermal method and analysed physically and electrochemically by utilizing different tests. XRD and FTIR were utilized to analyse structural nature and functional group of CuMn2O4/rGO/PANI. Thermal stability of CuMn2O4/rGO/PANI were analysed through TGA while their morphological was analysed by SEM analyser. Three-electrode system are utilized to analyse electrochemical characteristics of CuMn2O4/rGO/PANI through different parameters like galvanostatic charging and discharging, From GCD, Cs of CuMn2O4/rGO/PANI were calculated which show value of 1446.28 F g-1 and give value of Ed (47.05 Wh kg-1), Pd (242 W kg-1) at 1 A g-1. This work demonstrates that spinel with rGO and PANI proved an excellent material for the applications of SC and other energy storage devices.
