Facile fabrication of NiCo2O4/PANI nanocomposite for supercapacitors

The need for energy has increased globally as a result of recent industrial expansion. Supercapacitors are becoming more and more popular due to their exceptional qualities that can be used to meet energy demands. PANI/NiCo2O4 that has been hydrothermally produced is ideal for use as an electrode material. Several methods, like as charge-discharge along with electrochemical impedance spectroscopy, were applied to confirm its electrochemical parameters. The material PANI/NiCo2O4 nanocomposite showed better results compare to the NiCo2O4. According to the GCD results, the PANI/NiCo2O4 and NiCo2O4 demonstrated a specific capacitance of 1185.2 F/g and 577.7 F/g respectively. The resulting PANI/NiCo2O4 electrode material has 307 W/kg power density along with 62.1 Wh/kg energy density. The synthesized NiCo2O4/PANI exhibited exceptional retention following the 5000th cycle. According to the results, the composite material's electrochemical calculation was much better than that of the pure material, enabling more effective charge storage. The outstanding performance of PANI/NiCo2O4 nanomaterial indicates its considerable potential for upcoming technology for energy storage.
