摘要：

本工作通过比较不同存储期锌银电池中AgO的热力学特性、容量特性，研究AgO热稳定性以有效评价该类电池满足或拓展存储期限的可行性。本工作提出从不同恒速升温条件下的DSC曲线峰温和峰温时的反应深度计算/确定AgO分解反应动力学因子E、A的方法。建立数学模型，估算不同温度条件下锌银电池贮存期限并计算不同存储期锌银电池容量年衰减率，与不同温度下加速升温容量衰减率进行比较，最终确定适用于锌银电池加速寿命试验方法。

Abstract:

Through the comparison of different storage period, the thermodynamic characteristics of Zn-Ag battery AgO capacity characteristics, the effectiveness of the thermodynamic method study of AgO thermal stability and the feasibility of the battery to meet or expand the storage period are evaluated. Based on the he reaction depth at the peak and moderate peak temperature of DSC curve under different constant temperature heating conditions. A method for determining the kinetic factors E and A of AgO decomposition reaction was proposed. With the mathematical model, the decay rates of Zn-Ag battery with different storages period and under different temperatures were compared, and the method of accelerated life test for ffor Zn-Ag battery is got.
