The kinetics of electrode reaction was investigated by cyclic voltammetry, and cyclic voltammograms show that the reversibility of the Fe(bpy)₃²⁺/Fe(bpy)₃³⁺ electrode reaction is better than that of the Zn/Zn²⁺ electrode reaction on the graphite disc. However, the Fe(bpy)₃²⁺ ion diffusion in electrolyte is subject to greater resistance than that of the Zn²⁺ ion one. The stability of the Fe(bpy)₃Cl₂ solution was investigated by UV-vis spectroscopy, and the performance of a mild redox flow battery employing ZnCl₂ and Fe(bpy)₃Cl₂ in the NaCl aqueous solution with various membranes as the separator was also investigated. It was found that the Celgard 3501 membrane cannot effectively prevent Fe(bpy)₃²⁺ ions from leaking into anolyte, leading to the rapid failure of the flow battery. Although the Nafion 115 membrane can be polluted by Fe(bpy)₃²⁺ ions, it is not invalidated. The Nafion 115 membrane shows good selectivity, which can avoid Fe(bpy)₃²+ ions from leakage into anolyte. The ZnCl₂/Fe(bpy)₃Cl₂ flow battery with the Nafion 115 membrane exhibits the capacity retention of 80% after 200 cycles.

通过循环伏安法研究了电极反应的动力学，循环伏安图表明，Fe（bpy）₃ ²⁺ / Fe（bpy）₃ ³⁺电极反应的可逆性优于Zn / Zn ²⁺电极反应的可逆性在石墨盘上。然而，Fe（bpy）₃ ²⁺离子在电解质中的扩散比锌²⁺离子具有更大的电阻。通过紫外可见光谱研究了Fe（bpy）₃ Cl ₂溶液的稳定性，以及使用ZnCl ₂和Fe（bpy）₃ Cl ₂的温和氧化还原液流电池的性能。还研究了在NaCl水溶液中使用各种膜作为隔膜的情况。已经发现，Celgard 3501膜不能有效地防止Fe（bpy）₃ ²⁺离子泄漏到阳极电解液中，从而导致液流电池快速失效。尽管Nafion 115膜可被Fe（bpy）₃ ²⁺离子污染，但它不会失效。Nafion 115膜具有良好的选择性，可以避免Fe（bpy）₃ ² +离子泄漏到阳极液中。带有Nafion 115膜的ZnCl ₂ / Fe（bpy）₃ Cl ₂液流电池在200个循环后显示出80％的容量保持率。
