Abstract
Improvement of the conventional silver oxide electrode has been achieved by mixing with a certain amount of nanophase Ag2O particles. The periodic charge–discharge results of various electrode compositions under different discharge conditions (e.g., 1C, C/3 and C/10) provides a clear comparison of electrochemical performance. When the nanophase Ag2O species are between 10% and 35% of the active total amount, an extra 20–30% discharge capacity can be expected. However, if the electrode consists only of nanophase Ag2O as active material, it does not have effective charge–discharge cycles. The favourable role of nanophase Ag2O in a silver oxide electrode is attributed to the increased active material utilization because of optimum mass and charge transfer.
