Abstract
In this work we demonstrate the impact of synthesis conditions on the properties of stable nanostructured MnO2 and their application as electrode material in supercapacitors. Samples synthesized by hydrothermal method were characterized by XRD, XPS, SEM, BET surface area and the correlation with the electrochemical performance of constructed prototype supercapacitors was discussed. The morphological study of the as-synthesized MnO2 samples shown the morphology consisting of nanorods for pH value of 2.5 and cauliflower shape for pH of 3 and 6.5. The XRD study revealed that at low pH a α-MnO2 is formed whereas an increase of pH during synthesis leads to birnessite phase formation. The electrochemical studies, for 5 % KNO3 dissolved in dimethyl sulfoxide (DMSO) used as an electrolyte, shown that the birnessite MnO2 structure exhibits much better electrochemical behavior of constructed supercapacitors comparing to α-MnO2. The observed electrochemical behavior can be explained by the microstructure differences of prepared materials.
