适用于超级电容器应用的纳米氧化石墨烯/二氧化锰

The development of ultra-high performance energy systems that use electrochemical energy storage (EES) is a significant challenge facing the industry in the twenty-first century. The Mn 3 O 4 /Nano Graphene Oxide nanocomposite electrode material for the super capacitor application was fabricated in this article using a hydrothermal method, which results in safer, more efficient and faster electrical energy system materials. The composite of Mn 3 O 4 with Graphene Oxide electrode reduces its diffusive characteristics and enhances its capacitive behavior. X-ray diffraction analysis was performed to determine the particle size and crystal structure. SEM – Scanning electron microscope, Nano Graphene Oxide/Mn 3 O 4 semiconductor finds application in solar cells, optoelectronic and electronic devices. The electrochemical properties of the prepared electrode materials were studied by cyclic voltammetry in a 1 M KOH electrolyte solution. All the electrode materials exhibit Faradic reaction peaks in CV curves which imply the pseudo capacitive nature of the prepared materials. The prepared nanocomposite nano materials enchanted specific capacitance 139.95 Fg −1 at 1 Ag −1 . This improved electrochemical performance of attributed to the surface properties of nanostructure of metal oxide and an excellent conductive network. Dielectric characteristics of nanographene oxide/Mn 3 O 4 nanoparticles across numerous temperatures within the frequency range of 50 Hz to five MHz were investigated. The dielectric constant and dielectric loss show off minor frequency dependency at specific temperatures, yet up ward thrust as frequency increases. Electrical conductivity measurements imply that the dielectric properties of AC conductivity at different temperatures and frequencies for charge electricity quantity to − 1.2759 × 10 –6 .
