Abstract:Rechargeable silver-zinc batteries have aroused interest and find various area of usage depending on their notably technical advantages over other battery systems including their high specific energy and high recharge efficiency. In this battery chemistry, silver oxide and metallic zinc are used as the positive and negative active materials respectively. Chemically stabilized particles with large surface areas are needed to reach high discharge rates for battery applications. The use of nanoparticles as electrode materials has made a significant improvement in battery performance due to their enhanced electrical and chemical properties. In current study, we have successfully synthesized AgO nanoparticles through a sonochemical route. Parametric study was performed to examine the effect of reaction parameters such as reaction time, reaction temperature, and surfactant concentration on the quality of products. Synthesized AgO powder was characterized by particle size analyzer, X-ray diffraction (XRD), and scanning electron microscope (SEM). The AgO content of the prepared powder was 100 % and powder particle size mainly distribute in the range of 100-300 nm.
