Abstract:

Supercapacitors have acquired interest as energy storing devices because of their long-term stability, easy operation, fast charging/discharging rate, and high-power density. Here, we synthesized novel composite electrode material (Cu₂MgO₃/PANI) via hydrothermal method. Under 1 A/g, power density and specific capacitance (C_s) of Cu₂MgO₃/PANI are 649 F/g and 208 W/kg, accordingly. The higher specific surface area (SSA) and conductive polymer network of PANI are beneficial to promote electrical conductivity and ion migration in the Cu₂MgO₃ matrix. This enhancement, compared with pure Cu₂MgO₃ improves the charge storage capability and betterment in the electrochemical activity. The excellent electrochemical performance of Cu₂MgO₃/PANI predicts its promising future for electrochemical energy storage applications.
