Abstract. A precipitation method is proposed for the synthesis of nanostructured Mn oxide in the use of supercapacitor electrodes. Here, ethanol is used as a solvent, instead of water. The nanostructured Mn oxide synthesized has been characterized by various analytical methods. Experimental results reveal that the alkyl chain of ethanol plays an important role in forming the nanostructured Mn …
Abstract. A simple method for activating polyaniline (PANI) using NH3 for the synthesis of high performance electrode materials in supercapacitors is described. The PANI is activated at various temperatures (750–1050 ◦C) with a mixed stream of NH3 and N2. Because of the corrosive properties of NH3, the surface area of PANI (46.6 m2 g−1) is significantly increased up to 1719.8 m2 g−1…
