Abstract:

Iron-Chromium flow battery (ICFB) was the earliest flow battery. Because of the great advantages of low cost and wide temperature range, ICFB was considered to be one of the most promising technologies for large-scale energy storage, which will effectively solve the problems of connecting renewable energy to the grid, and help achieve carbon peak and carbon neutrality. Firstly, the main advantages of ICFB for large-scale energy storage are discussed, and the development and application of ICFB at home and abroad are introduced as well. Then, the technical bottlenecks of ICFB in the application of energy Storage were summarized and analyzed, including low energy efficiency due to poor electrochemical activity of chromium ion in the electrolyte, and poor stability due to the hydrogen evolution of the negative electrode at the end of charge process. Furthermore, the current research progress was described from four aspects, including electrolyte, electrode, membrane, and structure of flow battery. Finally, contrapose the limitation of ICFB, breakthroughs and innovations for the future ICFB are proposed to provide reference and basis for the development of ICFB, including improving key materials, optimizing design structure, and reducing battery cost.

Key words: iron-chromium flow battery, electrolyte, membrane, electrode
