Original Paper


The silver (П) oxide (AgO) powders as cathode material in Ag-based battery were synthesized with different dimensional ratios (DRs) and characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The SEM results indicated that AgO particles were slice in morphology. Also, the particle sizes were classified in three categories, including nanoscale with DR = 1 to 3, submicron/μm mixture with DR = 3 to 20 and nanoscale/submicron/μm mixture with DR = 3 to 15. The electrochemical performance of AgO particles as cathode active materials was investigated. The results of galvanostatic discharge at 80 mA/cm2 indicated that the highest capacity (400 mAh/g) and lowest potential drop were obtained for submicron/μm mixture of AgO particles. The best discharge performance at high current density (600 mA/cm2) was obtained for the cathodes prepared with high proportion of micron AgO particles.
