Redox Flow – Zn–Br

Abstract

This article covers zinc–bromine redox flow battery (ZBB) technology, which is a redox flow battery technology that is suitable for large‐scale energy storage. Due to its nonflammability, relatively high energy density, and modular design, the ZBB is now a promising candidate for energy storage systems on multi‐kW to MW scales. This article presents a thorough description of the electrochemical principle, major components, and structural design of ZBB. The information collected from a wide range of studies is organized in a new configuration to elicit the key features of ZBB technology and the issues involved in advanced ZBB technology.
