چکیده انگلیسی
Paper highlights, enhanced electrochemical performance of spray pyrolysed ruthenium (Ru) incorporated manganese-cobalt oxide (Mn: Co3O4) thin films, prepared via non aqueous route on to stainless-steel at 623â¯Â±â¯2â¯K. In the 1st phase of the work, prepared samples were characterized by XRD, SEM, TEM, SAED, EDAX and XPS and in the 2nd phase, samples were analyzed electrochemical characterizations. CV study shows mixed capacitive behavior for all electrodes. For optimized Ru-incorporation, prepared electrode exhibits maximum specific capacitance 1440.0â¯F/g at 1â¯mV/s scan rate in 1â¯M KOH. Excellent electrochemical stability is observed at 100â¯mV/s scan rate. Using charge-discharge study, the calculated values of specific energy, specific power and columbic efficiency were found as 1.1â¯Wh/kg, 2.80â¯kW/kg and 96.72% respectively. Electrochemical impedance measurement is scanned in the frequency range 1â¯mHz to 1â¯MHz. The internal resistance exhibited by the electrode as observed using Nyquist plot isââ¼1.12â¯Î©. By using ZsimpWin software, equivalent circuit was searched.
