银电极制备方法综述

Review of fabrication methods of silver oxide electrode

氧化银是一种适用范围很广的正极材料。与一些负极及电解液系统结合后,可以组成多种电化学体系并可满足高能量、高比能的要求。除了常见的锌电极,氧化银电极还可以与钙、铁、金属氯化物以及氢电极组成二次电源,或者与锂、铝电极组成一次电源。详细地介绍了银粉、氧化银粉的制备技术和控制因素,总结了烧结式氧化银电极和压成式氧化银电极在许多方面的不同点,并展望了未来氧化银电极的研究方向。

Silver oxide （AGO） cathode can be considered as one of the most versatile electrode materials. When coupled with other anodes and corresponding electrolyte management system, AgO electrode provides for a wide array of electrochemical systems that can be tailored to meet the high specific energy/energy density requirements. Besides zinc, the most notable include cadmium, iron, metal hydride, and hydrogen electrode for secondary systems, while primary systems include lithium and aluminum. The preparation procedure and control factor of Ag and AgO particles was introduced and the difference between sintered AgO electrode and pressed AgO electrode in many aspects was summarized. The development direction of the AgO electrode was discussed.
