Abstract:

The rapid progress and significant increase in population have surged the use of natural resources to fulfil the energy necessities. To provide a clean, eco-friendly and continuous energy supply, the supercapacitors are superior and affordable choice. This study seeks to boost the electrochemical properties of MgZrO₃ with polyaniline which is synthesized by cost-effective hydrothermal method. We employed a range of physicochemical tools to observe the physical properties of the fabricated nanoparticles, like X-Ray diffractometer and scanning electron microscope to utilize the Structural and morphological behaviour. The three electrodes system are utilized to test their remarkable electrochemical properties. The assessment at 1 A/g revealed that the specific capacitance (C_s) of the MgZrO₃/PANI nanocomposite electrode was 1881.03 F/g. The excellent electrochemical behaviour of the nanohybrid results from the synergistic behaviour of PANI on MgZrO₃ particles which resulted the minimum solution resistance value 0.92 Ω of MgZrO₃/PANI composite. Hence, the resulting electrode is efficient and more stable, and can be used for future generation energy conversion and storage devices.
