Here, we demonstrate a simple and comparatively low temperature synthesis of functionalized multilayer fullerenes so called carbon nano-onions (CNOs) as the electrode for high performance electrochemical supercapacitors. The exohedral type supercapacitor formed due to nonporous CNOs showed higher specific capacitance than conventional graphitic/mesoporous/activated carbons. Surface redox functionalities of these CNOs add up to significant pseudocapacitance. Further in situ incorporation of MnO2 nanoparticles to these CNOs increased the specific capacitance up to 1207 F g(-1), which is close to the theoretical value of pseudocapacitive MnO2.</p>1 aAzhagan, Muniraj, Vedi Kuyil1 aVaishampayan, Mukta, V.1 aShelke, Manjusha, V.  uhttps://library.ncl.res.in/content/synthesis-and-electrochemistry-pseudocapacitive-multilayer-fullerenes-and-mno2-2
