Large size ordered structure AgO electrode materials were prepared by an electrochemical method. The crystal structure, phase composition, microstructure, formation mechanism and discharge properties of samples were investigated. The results of crystal structure and phase composition show that AgO material synthesized has a strong (002) orientation and a relatively high purity phase. The results of microstructure indicate that AgO material has an ordered columnar arrangement structure with a straight-through hollow structure and a column diameter of 1-3 μm, which is conducive to the electrolyte diffusion. Based on the results of thermal analysis, the purity of AgO material is higher than 98.5%. Under the action of electric field force and gas evolution, AgO material forms an ordered columnar structure through self-assembly, which is conducive to the diffusion of electrolyte solution in the electrode and greatly improves the discharge performance of the large size AgO electrode. The average voltage of AgO electrode is 1.67 V and the electrochemical utilization ratio is 75.6% when the discharge current density is 770 mA/cm2 and the cut-off voltage is 1.5 V, enhancing the high-rate discharge performance and utilization. Realizing a small-batch preparation of large-size AgO electrode material can meet the requirement of industrial production and application.

利用电化学法制备了大尺寸有序结构的AgO电极材料,对样品的晶体结构、物相组成、微观结构、形成机理以及放电性能进行了研究。结果表明:制备的AgO材料具有较强的(002)取向,无其他杂相存在。在电场力和气体析出的共同作用下,AgO材料通过自组装定向排列形成有序柱状结构,柱直径为1~3 μm,这种结构有利于电解质溶液在电极中的扩散,降低极化效应,使得大尺寸AgO电极的放电性能大幅度提高。AgO电极在770 mA/cm2的放电电流密度下,放电截止电压1.5 V时的平均电压为1.67 V,电化学利用率为75.6%,提高了大倍率放电性能和利用率。实现大尺寸AgO电极材料小批量制备,能够满足工业化生产和应用。

利用电化学法制备了大尺寸有序结构的AgO电极材料,对样品的晶体结构、物相组成、微观结构、形成机理以及放电性能进行了研究。结果表明:制备的AgO材料具有较强的(002)取向,无其他杂相存在。在电场力和气体析出的共同作用下,AgO材料通过自组装定向排列形成有序柱状结构,柱直径为1~3 μm,这种结构有利于电解质溶液在电极中的扩散,降低极化效应,使得大尺寸AgO电极的放电性能大幅度提高。AgO电极在770 mA/cm2的放电电流密度下,放电截止电压1.5 V时的平均电压为1.67 V,电化学利用率为75.6%,提高了大倍率放电性能和利用率。实现大尺寸AgO电极材料小批量制备,能够满足工业化生产和应用。

Large size ordered structure AgO electrode materials were prepared by an electrochemical method. The crystal structure, phase composition, microstructure, formation mechanism and discharge properties of samples were investigated. The results of crystal structure and phase composition show that AgO material synthesized has a strong (002) orientation and a relatively high purity phase. The results of microstructure indicate that AgO material has an ordered columnar arrangement structure with a straight-through hollow structure and a column diameter of 1-3 μm, which is conducive to the electrolyte diffusion. Based on the results of thermal analysis, the purity of AgO material is higher than 98.5%. Under the action of electric field force and gas evolution, AgO material forms an ordered columnar structure through self-assembly, which is conducive to the diffusion of electrolyte solution in the electrode and greatly improves the discharge performance of the large size AgO electrode. The average voltage of AgO electrode is 1.67 V and the electrochemical utilization ratio is 75.6% when the discharge current density is 770 mA/cm2 and the cut-off voltage is 1.5 V, enhancing the high-rate discharge performance and utilization. Realizing a small-batch preparation of large-size AgO electrode material can meet the requirement of industrial production and application.
