New electrode material for energy storage devices -synthesis and electrochemical characterization

SEEE DIGIBOOK ON ENGINEERING & TECHNOLOGY, VOL. 01, FEB 2018 PP.(144-146)
Abstract– New graphene/Mn3O4nano composite usable for portable supercapacitor have been synthesized using pyrolysis technique. The material has been characterized by FTIR, XRD, CV, and GCD analysis. The nano composite has nano Mn3O4in the size 96nm embedded in graphene and posses specific capacitance of about 130F/g. Which could be retained for 1.1mintues giving a power density of 180w/kg.
