Fabrication of a Novel Polymer Nanohybrid Electrode Material PANI-BaMnO3 for High Power Supercapacitor Application

Abstract

The electro active inorganic-organic nanohybrid material Polyaniline-BaMnO3 has been synthesized by the surfactant assisted chemical polymerization reaction of aniline with nanocrystalline BaMnO3.Electrochemical studies have been performed using cyclic voltammetry and galvanostatic charge-discharge measurements.The enhanced electrode performance originates from the synergistic effect of PANI and BaMnO3.The hybrid delivers very high specific capacitance of 560.5 Fg -1 , energy density of 32.01 whkg -1 and power density of 400 wkg -1 , respectively.The hybrid also exhibits very high stability and excellent cycling performance with less than 5% capacity loss over 500 cycles.
