Abstract
Supercapacitors have been given significant consideration as advanced energy storage devices owing to their rapid charging capabilities, exceptional stability, and high retention performance, aligning with the demands of modern technologies. In the current investigation, a hybrid nanocomposite containing MnO2 nanorods anchored onto reduced graphene oxide (rGO) was made via a hydrothermal route, demonstrating superior supercapacitive behavior. The nanocomposite was extensively characterized through functional, structural, morphological, and electrochemical analyses, and subsequently utilized as supercapacitor electrode material. Electrochemical evaluations were conducted in a 3-electrode system using the electrolyte of 1 M Na2SO4, revealing an impressive specific capacitance of about 398 F g-1. Notably, the electrode exhibited remarkable long-term stability, with a retention value of 94% after 5000 charge–discharge cycles. These results position the rGO-MnO2 hybrid as an auspicious candidate for future supercapacitor applications.
期刊介绍:
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
