SHANMUGAVADIVEL, M; DHAYABARAN, V. Violet  e  SUBRAMANIAN, M. Fabrication of a Novel Polymer Nanohybrid Electrode Material PANI-BaMnO3 for High Power Supercapacitor Application. Port. Electrochim. Acta [online]. 2017, vol.35, n.4, pp.225-232. ISSN 0872-1904.  https://doi.org/10.4152/pea.201704225.

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.
