Redox Flow Batteries

Abstract

Redox flow batteries (RFBs) possess numerous merits over alternative energy storage technologies, making them a compelling solution for large-scale storage systems. Their appealing features encompass scalability and flexibility, independent power and energy sizing, high round-trip efficiency, remarkable durability, and swift responsiveness. These attributes render them ideally suited for bolstering electricity generation from renewable energy sources, as they can accommodate a broad spectrum of operating and discharge times. Owing to their expandable electrolyte storage tanks, RFBs are increasingly considered a propitious solution for large-scale energy storage systems in applications such as backup power systems and surplus energy storage. This chapter aims to provide a succinct, comprehensive review of RFB technology to expedite the reader's understanding. We begin by introducing the operating mechanisms of RFBs, followed by a comprehensive review of electrode materials utilized in both aqueous and nonaqueous RFBs. Additionally, we detail the membranes suitable for both aqueous and nonaqueous RFBs, enabling readers to gain a well-rounded understanding of this promising energy storage technology.
