Abstract
This study explores the synthesis of rod-like manganese-copper-cobalt (MCC) composites through a hydrothermal process, resulting in visually appealing morphologies. The synthesized MCC nanocomposites characterization through various techniques. The analysis confirmed the incorporation of transition-metal oxides in metallic composites in the desired oxidation states. The electrochemical performance of the rod-like MCC composites was evaluated. The results revealed impressive pseudocapacitance characteristics, with a high specific capacitance of 670.31 Fg−1 at 5 mVs−1 and excellent cycling stability, retaining 91 % capacitance even after 5000 cycles. Further calculations demonstrated notable areal-specific capacitance (231.38 mFcm−2), energy density (0.0157 mWh cm−2), and power density (0.1487 mW cm−2) for the MCC composites. These findings demonstrate the potential of well-morphologically established MCC composites as capable electrode materials for energy storage in electrochemical supercapacitors.
