Abstract:

The research and development of advanced nanostructured devices are globally important endeavour, which provides an exciting approach for producing clean, renewable energy. Transition metal selenides have abundant active sites and elevated electrical conductivity. Polyaniline (PANI) has drawn increased interest as potential material for energy storage regarding to its significant specific capacitance and strong electrochemical reversibility. Thus, the combination of transition metal selenide and PANI is a practical choice for energy storage devices. In this research, we have created ZnSe/PANI nanocomposite by utilising a simple hydrothermal technique. The physical and electrochemical parameters of fabricated materials are obtained through several techniques. Electrical conductivity was enhanced due to the active sites in ZnSe/PANI, producing a synergetic effect in composite material. ZnSe/PANI nanomaterial demonstrated an effectively elevated specific capacitance of 605.38 F g⁻¹ at 1 A g⁻¹. The synthesised ZnSe/PANI had an energy density of 38.21 Wh kg⁻¹ and power density of 343.9 W kg⁻¹. The significant specific capacitance and straightforward one-step fabrication method of ZnSe/PANI demonstrated its effectiveness as an electrode material for use in supercapacitor.
