摘要
氧化银的不稳定性是导致铝氧化银贮备电池在干态、未激活的状态下长期储存容量减少、激活时间延长的主要原因。通过加速老化实验测得电化学方法制备的氧化银的分解动力学参数,并通过建立模型计算氧化银的分解速率,以此来预测铝氧化银贮备电池中氧化银电极的储存寿命。
The instability of silver（Ⅱ） oxide electrodes used in silver oxide/aluminum reserve batteries is the well-known cause of capacity loss and the delayed activation in reserve batteries after stored in the dry and inactivated state for the extended periods of time.The decomposition kinetics of the thermodynamically unstable AgO component of silver oxide cathodes used in silver/aluminum reverse batteries was determined by a rapid and accelerated-aging thermogravimetry（TG） technique.The calculated decomposition rates of AgO could be used to predict the storage life time of primary,and reserve silver oxide/aluminum reserve batteries.
