A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion transfer inside the cell (accompanied by current flow through an external circuit) occurs across the membrane while the liquids circul. HistoryThe (Zn–Br2) was the original flow battery. John Doyle file patent on September 29,. . A flow battery is a rechargeable in which an containing one or more dissolved electroactive elements flows through an that reversibly converts to . Redox flow batteries, and to a lesser extent hybrid flow batteries, have the advantages of: • Independent scaling of energy (tanks) and power (stack), which allows for a cost/weight. .
