In this article, we will explore the evolution of flow battery technology and shed light on the latest advancements that are shaping its future.
A Brief Overview of Flow Batteries
Flow batteries are energy storage systems that store chemical energy in external tanks, separate from the electrical conversion hardware. They operate by pumping electrolyte solutions through a cell stack, where chemical reactions take place, generating electricity. Unlike conventional batteries, flow batteries offer the advantage of separable energy and power capacity, meaning they can be easily scaled to meet specific needs.
These innovative systems have gained popularity due to their extended lifespan, flexibility, and ability to store large amounts of energy. Several types of flow batteries exist, including the vanadium redox flow batteries (VRFBs), zinc-bromine flow batteries (ZBFBs), and iron-chromium flow batteries (ICFBs), each with its unique chemistry and performance characteristics.
