Effects of Sintering Temperature and Press Pressure on the Microstructure and Electrochemical Behaviour of the Ag2O/GO Nanocomposite

Resumo

The purpose of this study was to evaluate the effects of press pressure and sintering temperature on the microstructure and electrochemical performance of silver oxide-graphene oxide composite as a novel electrode produced by the powder metallurgy (PM) route. Scanning electron microscopy method used to investigate the microstructure of electrodes and energy dispersive X-ray spectroscopy analysis method was used for point analysis. Potentiodynamic polarization and electrochemical impedance spectroscopy methods were used to research the effects of sintering temperature and press pressure on the electrochemical behaviour in the 1.4 wt % KOH solution and electrical discharge test was used for evaluate the ultimate electrical capacity of silver oxide-zinc batteries with electrolyte of the 1.4 wt % KOH solution.
