Cadmium-doped manganese ferrite nanoparticles were synthesised by the co-precipitation method. The prepared sample was annealed at various temperatures, including 400°C, 600°C, and 700°C.The ideal temperature was determined to be 700°C based on TG/DT analysis, and additional analysis was prepared for the sample at a temperature of 700°C. XRD, SEM, HR-TEM, CV, BET, FTIR, EDX, and XPS techniques were used to analyse their morphology and characteristics. Functional group identification via FTIR spectroscopy. The presence of employed material lacking any contaminants was confirmed by the energy-dispersive X-ray Spectroscopy outcomes. The prepared sample's structural parameters were examined using the X-ray diffraction technique. Using the Debye-Scherrer equation, it was determined that the average crystalline size was 39 nm. By employing cyclic voltammetry (CV), the electrochemical characteristics of the sample are investigated. The outcomes show that for the lower scan, 2mVs-1, there is a greater capacitance value of 365.12Fg-1, which is recommended for use in supercapacitors.
