In standard flow batteries, two liquid electrolytes—typically containing metals such as vanadium or iron—undergo electrochemical reductions and oxidations as they are charged and then discharged.
A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes. [1]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.
