Abstract

Nano materials with high surface area increase the kinetics and extent of the redox reactions, thus resulting in high power and energy densities. In this study, ZnO nanorods was prepared by hydrothermal method and used as an anode for zinc-silver battery. These nanorods are characterized by XRD, SEM, specific surface area analysis, solubility in alkaline, EDX analysis and galvanostatic charge/discharge studies in zinc-silver batteries. The electrochemical measurements of nano ZnO negative electrode in the zinc-silver secondary battery exhibited a stable cycle performance with a discharge capacity of 500 mAh g−1 after 100 cycles that it was 120 mAh g−1 higher than the capacity of bare ZnO. Keywords: ZnO. Zinc- silver batteries. Anode. Hydrothermal method.
