Hydrothermal synthesis of ZnBi2O4/PANI nanocomposite: a high-performance electrode material for next-generation supercapacitors

Researchers are always developing new, ultrahigh-performance energy storage materials because of their ongoing quest for quicker and more effective energy storage techniques. Optimizing the attributes of electrode material could be beneficial in resolving these problems. Spinel composites comprised of polyaniline are used in various applications, notably energy storage systems. ZnBi₂O₄/PANI nanocomposite has been synthesised by an easy hydrothermal technique for supercapacitor application. Several analytical approaches have been utilised to evaluate the nanocomposite physico-chemical characteristics carefully. The ZnBi₂O₄/PANI showed a better electrochemical characterisation with specific capacitance of 1110.12 F/g at 1 A/g. The newly constructed electrode performed better because of its enhanced surface area, better morphology, and increased electrochemical conductivity, and it exhibited a remarkably large energy density of 48.87 Wh/kg and power density of 281.5 W/kg. ZnBi₂O₄/PANI exhibits superior electrochemical properties because of its substantial surface area, lower resistance, and faster electrolytic ion flow than the individual components. As such, the ZnBi₂O₄/PANI shows potential as an electrode material to be utilized in a range of commercial applications, as well as electrodes for upcoming energy storage technologies.
