Flow batteries are electrochemical cells, in which the reacting substances are stored in electrolyte solutions external to the battery cell Electrolytes are pumped through the cells Electrolytes flow across the electrodes Reactions occur atthe electrodes Electrodes do not undergo a physical change Source: EPRI K.

Schematics representing the electrochemical reactions in the iron/chrome redox battery. Most redox flow batteries consist of two separate electrolytes, one storing the electro-active materials for the negative electrode reactions and the other for the positive electrode reactions.
Most redox flow batteries consist of two separate electrolytes, one storing the electro-active materials for the negative electrode reactions and the other for the positive electrode reactions. (To prevent confusion, the negative electrode is the anode and the positive electrode is the cathode during discharge.
Flow Battery Characteristics Relatively low specific power and specific energy Best suited for fixed (non-mobile) utility-scale applications Energystorage capacity and powerrating are decoupled Cell stack properties and geometry determine power Volume of electrolyte in external tanks determines energy storage capacity
