摘要: Experimental results on cathodic electrosynthesis of MnO2 electrodes for electrochemical supercapacitors are presented. The deposition yield data at different pulse durations and mechanism discussed. Electron microscopy investigations show porous structure the electrodes, which is beneficial good electrolyte access to active material. capacitance 2.6 F cm–2 (199 F g–1), energy density 20 Wh kg–1 power 28 kW kg–1 achieved 13 mg cm–2 electrodes. improved retention high scan rates. Ni plaque-based promising storage applications in supercapacitors.
