Abstract
The ferro-/ferricyanide couple has been extensively investigated as a redox species in various redox flow batteries (RFBs) due to its advantageous electrochemical properties, user-friendliness, and affordable cost. However, the high concentration and stability of ferro-/ferricyanide are important for developing high-energy density and long-cycle life RFBs. Different methods have been explored to increase its concentration through diverse ion effects and cation modification while also exploring the effects of pH, light, and air sensitivity on its stability. This review will provide an overview of recent research on the concentration enhancement of ferro-/ferricyanide and its stability for RFBs.
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 •
