Preparation and testing of CeFe2O4@PANI nanocomposite, as pseudo-capacitor electrode for energy storage applications
摘要
The global demand for meetings requires energy, and the influence on energy storage technology is critical to provide a consistent energy supply. Supercapacitors have recently fascinated researchers’ interest as potential alternative for electrochemical energy storage strategies. This study focuses on production of CeFe2O4@PANI nanocomposite for supercapacitor devices using hydrothermal approach. Many physical and electrochemical analytical tests were utilised to characterise manufactured nanocomposite. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were then utilized to analyse structure, functional group confirmation and morphology of material. Moreover, composite was tested in KOH, which confirmed its outstanding electrochemical characteristics. GCD confirmed good specific capacitance 948 F g− 1 at 1.0 A g− 1 with energy density (Ed) of 16.13 Wh kg–1. This study not only shows potential of CeFe2O4@PANI as a supercapacitor electrode, but also focusses on building low-cost nanocomposites with excellent performance that might be used for variety of applications in future.
