Abstract:

Redox flow batteries have a number of advantages for electrical energy storage, including high roundtrip efficiency, long service life and suitable for large scale applications. Such a type of energy storage devices have a wide range of applications in the use of renewable energy sources such as wind and solar, smart grid and microgrid. This paper presents a brief review of the state-of-the-art development of the redox flow batteries. Major technological barriers are discussed. Future directions of research and development are proposed.
