可溶铅酸液流电池模拟与仿真

摘要可溶铅酸液流电池是一种使用单个容器存储电解液并且不需要微孔隔膜的氧化还原液流电池，这使得电池设计简单并降低了成本。建立二维暂态可溶铅酸液流电池模型，模型基于对质量、电荷以及能量的转移与守恒以及包含铅离子反应的宏观动力学模型为基础，研究了电极间隔、电极形状、电流密度、实验温度、入口电解液流速和电解质初始浓度对电池性能的影响。研究表明：与平板电极相比，弧形电极明显提高了充电时的电池电压。在影响铅酸液流电池性能的诸多条件中，电池温度和电流密度可能是优化电池性能的重要因素。

Abstract： The soluble lead-acid battery is a redox flow cell that uses a single reservoir to store the electrolyte and does not require a microporous separator or membrane, allowing a simpler design and a substantical reduction in cost. In this paper, a two-dimensional transient model for a soluble lead-acid flow battery is developed. The model based on a comprehensive description of mass, charge, energy and momentum transport and conservation, and is combined with a global kinetic model for reactions involving lead species. The influences of the electrode gap, electrode shape, applied current density, operating temperature; inlet electrolyte velocity and initial concentration of species on the charge/discharge behavior of the cell are investigated. The results show that compared with the plate eleoctrode, the camber electrode makes the voltage during charging risen remarkably. Among various conditions that affect the performance of the soluble lead-acid flow battery, operating temperature and current density may be the keys in optimizing a lead-acid flow battery.
