Abstract
The effort of searching for a new stable oxide electrode for supercapacitor is extensively performed. For the conventional capacitor, the capacitive storage could be strongly depend on high dielectric materials. Besides the high capacity, the release rate is one of the crucial issue for supercapacitor. For the latest case, we should improve a total conductivity of introduce other ionic materials in the system. The high ferroelectric materials of perovskite ATiO3 could candidate for high capacitive materials by introducing FC (Functionalized Carbon) with FC stands for enhancing the conductivity and dielectric constant of composite. The new known common supercapacitor materials of FC (Graphene, Acetylene Carbon Black), Mn2O3, and ATiO3 could be a good candidate for high energy density supercapacitor. The new integrated thermoelectric-supercapacitor device lately introduced due to the implementation of thermoelectric under magnetic field. ATiO3 has been synthesized using conventional solid-state reaction with intermediate calcination. The composite FC/Mn2O3/ATiO3 with ethanol adhesive has been fabricated using conventional die pressed. The capacitance as a function of magnetic field was characterized using DC capacitance meter under various magnetic field generated by double coil magnetic generator.
