A flow battery is a type of rechargeable battery where electrolyte liquids are pumped through the system to create an electrochemical reaction. Flow batteries are often used in large-scale energy storage applications.
Some of the emerging trends in flow batteries include the use of vanadium redox flow batteries (VRFBs) for large-scale energy storage, the use of zinc-bromine flow batteries (ZBFBs) for grid-scale energy storage, and the use of proton exchange membrane flow batteries (PEMFBs) for portable energy storage.
