Abstract

The behavior of a silver electrode, which is reversible with respect to minority carriers, in a sulfate solid electrolyte or the corresponding ionic melt is studied in the galvanodynamic mode using Laplace transform of Ohm’s law on the interaction between current, potential, and impedance, which is called the operational impedance method in electrochemistry and electrical engineering. In addition to the operator impedance method, we also use an equivalent electrical circuit of a silver electrode, which is reversible with respect to oxygen and minority carriers (i.e., oxygen ions). The possibility of using equivalent electrical circuits in studying the relaxation processes in solid electrolytes was shown in 1973 [9, 10]. An analytical expression is obtained for the time dependence of the potential of the electrode–solid electrolyte (or corresponding ionic melt) interface in the galvanodynamic mode of operation of an electrochemical cell. As shown by a graphical–analytical analysis, the galvanodynamic time dependence of the interface potential is an exponential function. The difference between a silver electrode in sulfate electrolytes and the classical equivalent Erschler–Randles electrical circuit is shown to consist in the fact that the silver electrode performs another function, namely, an oxygen function, at very low silver ion concentrations.

摘要

使用电流，电位和阻抗之间相互作用的欧姆定律的拉普拉斯变换，通过电流动力学模式研究了在硫酸盐固体电解质或相应的离子熔体中相对于少数载流子可逆的银电极的行为。在电化学和电气工程中称为操作阻抗法。除了操作员阻抗方法外，我们还使用银电极的等效电路，该电路相对于氧气和少数载流子（即，氧离子）是可逆的。1973年显示了使用等效电路研究固体电解质的弛豫过程的可能性[9，10]。在电化学电池运行的电流动力模式下，获得了电极-固体电解质（或相应的离子熔体）界面电位的时间依赖性的解析表达式。如图形分析所示，界面电位的电动动力学时间依赖性是指数函数。硫酸盐电解质中的银电极与经典等效的埃施勒-兰德斯电路之间的差异表明，在非常低的银离子浓度下，银电极还具有另一种功能，即氧气功能。界面电位的电动动力学时间依赖性是指数函数。硫酸盐电解质中的银电极与经典等效的埃施勒-兰德斯电路之间的差异表明，在非常低的银离子浓度下，银电极还具有另一种功能，即氧气功能。界面电位的电动动力学时间依赖性是指数函数。硫酸盐电解质中的银电极与经典等效的埃施勒-兰德斯电路之间的差异表明，在非常低的银离子浓度下，银电极还具有另一种功能，即氧气功能。
