Flow batteries are a type of electrochemical ES, which consists of two chemical components dissolved in liquid separated by a membrane. Charging and discharging of batteries occur by ion transferring from one component to another component through the membrane. The biggest advantages of flow batteries are the capability of pack in large volumes.

7. Concluding remarks and perspectives Flow batteries are regarded as one of the most promising large-scale energy storage technologies because of their site-independency, decoupling of power and energy, design flexibility, long cycle life, and high safety.
High-capacity flow batteries, which have giant tanks of electrolytes, have capable of storing a large amount of electricity. However, the biggest issue to use flow batteries is the high cost of the materials used in them, such as vanadium. Some recent works show the possibility of the use of flow batteries.
In contrast with conventional batteries, flow batteries store energy in the electrolyte solutions. Therefore, the power and energy ratings are independent, the storage capacity being determined by the quantity of electrolyte used and the power rating determined by the active area of the cell stack.
In contrast, the capacity of a flow battery can be simply increased by increasing the size of the external storage tanks of the electro-active materials. A flow battery is an electrochemical device that converts the chemical energy of the electro-active materials directly to electrical energy, similar to a conventional battery and fuel cell.
