Abstract:

In this research, manganese selenide (MnSe) and MnSe/PANI nanocomposites were fabricated using the hydrothermal technique. Phase analyses and the structure of synthetic materials were examined using X-ray diffraction. Scanning electron microscopy research demonstrated that MnSe on PANI sheets successfully formed a nanosheets-like morphology, offering a conductive route for electrolyte ion exchange. MnSe/PANI has specific capacitance (C_s) and its power density (P_d) delivered 1377.36 F/g and 265 Wkg with solution resistance (R_s) of MnSe/PANI was 0.70 Ω smaller than MnSe (0.96 Ω), as demonstrated by the Nyquist plot. By adding PANI to MnSe, conductivity and capacitance was improved due to faster charge ion transport. The MnSe/PANI nanocomposite demonstrated outstanding stability throughout the 5000^th cycle. For supercapacitors and other energy storage applications, MnSe/PANI nanocomposite is a excellent choice in various electrodes.
