摘　　要：锌银蓄电池具有一系列优异的电化学性能(比能量高、内阻小等),使其在航空航天等应用领域中始终保持重要的地位。从锌银蓄电池的关键部件——氧化银电极的制备和应用研究现状,根据氧化银电极的性能直接影响电池的工作效能和寿命,提出了氧化银电极应用中所面临的问题:即高阶电压段、银迁移及过氧化银分解等,综述了解决这些问题的方法和改进措施,并探讨了锌银蓄电池中氧化银电极的未来研究方向和发展趋势。Silver-zinc storage batteries play an importance role in aeronautics, astronautics and other special fields because of their superiority in electrochemical performances, such as high specific energy, minor internal resistance, etc. Silver oxide electrode is the key component of silver-zinc storage battery. Because the performances of silver oxide electrode directly affect its operation and longevity, this paper describes the current development status of the preparation and application of silver oxide electrodes, and presents some problems for their applications, such as the high voltage plateau, the silver migration and the decomposition of divalent. Some methods and approaches to solve these problems are mentioned. Finally the prospects and directions for the development of silver oxide electrode are also discussed.
