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.

“…4a) is associated with the (021) lattice plane of JCPDS card no. 53-1891, both are associated with the orthorhombic crystal structure [47][48][49][50][51][52].This small degree of crystallinity is ascribed to the periodicity of benzenoid and quinoid rings present in the PANI structure [53,54]. Furthermore, P-3 was subjected to the FT-IR analysis as shown in Fig.…”
