Iron-chromium flow batteries represent a significant category of redox flow battery technology that utilizes the redox couples of iron (Fe2+/Fe3+) and chromium (Cr2+/Cr3+) in a hydrochloric acid electrolyte. Energy is stored by employing the Fe2+ – Fe3+ and Cr2+ – Cr3+ redox couples. The active chemical species are fully dissolved in the aqueous electrolyte at all times. Powering a Decarbonised Future. Annual investment in energy storage must grow more than 15x to meet climate goals (IEA, World Energy Investment 2023). These systems have been studied for decades due to their potential for large-scale energy. . The Iron Redox Flow Battery (IRFB), also known as Iron Salt Battery (ISB), stores and releases energy through the electrochemical reaction of iron salt. This type of battery belongs to the class of redox-flow batteries (RFB), which are alternative solutions to Lithium-Ion Batteries (LIB) for. . Among the many energy storage technologies, iron chromium flow battery is a large-scale energy storage technology with great development potential. Unlike solid-state batteries, flow batteries separate energy storage from power delivery, allowing for independent scalability, longer lifetimes, and reduced. .
