| Abstract: | Reduced graphene oxide (rGO) is widely recognized for its superior electrical conductivity, extensive surface area, and adaptability. It has high energy storage capability and a wide range of applications. Its utility in crafting lightweight hybrid electrodes for pseudocapacitors is especially significant, facilitating enhanced charge storage and power output. However, the reduction in accessible area, lower specific capacitance, and power density are major difficulties, which can be overcome by integrating a constant percentage of carbon nanotubes (CNT) and varying concentrations of manganese dioxide (MnO2) via a vacuum filtration route. This study reports the production and analysis of five different compositions: pure rGO, rGO with 8% CNTs, and rGO with 8% CNTs along with 10%, 20%, and 30% MnO2. CNTs acted as effective conductive spacers, and MnO2 served as a redox-active material. The fabricated electrode compositions underwent characterization of various parameters including sheet resistance, conductivity, Brunauer–Emmett–Teller (BET) surface area, specific capacitance, power density, and equivalent series resistance (ESR). The results showed that the rGO-based pseudocapacitive material embedded with 8% CNTs and 20% MnO2 yielded distinct functional properties including lower sheet resistance of 70 Ω/sq, higher current density of 1.41 S/cm, and improved BET surface area of 310 m2/g, with specific capacitance of 318 F/g, power density of 943 W/kg, and moderate ESR of 1.9 Ω. The results showed significant enhancements in electrical and electrochemical performance, thereby positioning rGO/CNT/MnO2 hybrids as a promising candidate for advanced lightweight electrode applications.
