摘　　要：在Zn/AgO贮备电池体系中,硅酸钠用作一种热稳定剂包覆在化学合成的AgO颗粒表面,能够很好地抑制AgO材料的热分解,却对Zn/AgO贮备电池的快速激活特性存在一定的影响。研究了硅酸钠相对含量对化学合成AgO正极材料的恒流极化性能的影响:硅酸钠相对含量越少,AgO正极材料恒流极化越小;组装成电池的放电结果与AgO正极材料恒流极化性能存在一定的相关性:硅酸钠含量相对较少,电池的快速激活性能较好,反映了其相对含量对Zn/AgO贮备电池快速激活性能的影响程度,为Zn/AgO贮备电池体系AgO正极材料的制备提供一定的参考。Sodium silicate is used as thermal stabilizing reagent in Zn/AgO reserve battery which coats the chemical synthesized AgO grain to restrain its decomposing while affecting the fast-activating property of reserve battery as well. The influence of the relative content of Na2SiO3 on constant current polarization of the AgO was first investigated. The results indicate that the less the relative content of Na2SiO3, the less the AgO-anode polarized; between which some relativity is found with the discharge property of the assembled batteries; the less the relative content of Na2SiO3, the better the fast-activating property of the batteries. These results to some extent reflected its effect upon the fast-activating property of the Zn/AgO reserve battery, providing future reference to the preparation of the AgO anode material.
