Abstract

The cost of active material for all-vanadium flow batteries is high, so that all-iron flow batteries (AIFBs) may be a good choice for decreasing the cost of redox flow batteries. However, there are some problems such as iron dendrite and hydrogen evolution in acidic AIFBs, and hydrolysis and precipitation of iron hydroxide in alkaline AIFBs. This review reveals the underlying causes of these problems, and summarizes recent researchers’ solutions to these problems. In addition, this review discusses the effect of different ligands on the electrode potential of negolytes and raises prospects for the future trends of research on the AIFBs.

全铁液流电池的研究进展

全钒液流电池的活性材料成本较高，因此全铁液流电池可能是降低氧化还原液流电池成本的一个很好的选择。但酸性AIFBs存在铁枝晶和析氢问题，碱性AIFBs存在氢氧化铁水解和沉淀问题。这篇综述揭示了这些问题的潜在原因，并总结了近年来研究人员对这些问题的解决方案。此外，本文还讨论了不同配体对未成熟细胞电极电位的影响，并对其未来的研究趋势进行了展望。

期刊介绍： The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
