摘要

An economical and environmental friendly energy storage device is the best way to address issues like pollution and the world energy crisis. For supercapacitor applications, electrode materials with high specific capacitance (Csp) that are effective, stable and sustainable must be developed. Here, SrCr2O4/PANI was prepared hydrothermally for use as a charge storage medium in supercapacitors. Electrochemical properties of developed material were computed using GCD and CV in a 3 M KOH. Electrode made of SrCr2O4/PANI exhibited faradaic behaviour, obtaining specific capacitance (Cs=1289.37 F/g), while pure SrCr2O4 revealed lower Cs of 648.48 F/g. Polyaniline (PANI) caused an increased Cs and conductivity of material due to its greater surface area and improved electrical conduction. These findings suggest that the SrCr2O4/PANI nanocomposite may be a good choice for a reliable and quick supercapacitor electrode. The capacitive feature of SrCr2O4/PANI electrode was enhanced with change in structural and electronic arrangement, modification in morphology and integration of carbon based materials. According to this study, adding PANI to a SrCr2O4 nanoarray enhances energy storage performance and efficiently used in other energy storage systems.
