Vanadium redox flow batteries (VRFBs) have emerged as a leading solution, distinguished by their use of redox reactions involving vanadium ions in electrolytes stored separately and circulated through a cell stack during operation. This design decouples power and energy, allowing flexible scalability for various applications.
Compared to inorganic redox flow batteries, such as vanadium and Zn-Br2 batteries, organic redox flow batteries' advantage is the tunable redox properties of their active components. As of 2021, organic RFB experienced low durability (i.e. calendar or cycle life, or both) and have not been demonstrated on a commercial scale. Organic redox flow batteries can be further classified into aqueous (AORFBs) and non-aqueou.
