A Flow Cell Battery (or Redox Flow Battery) is a rechargeable battery comprised two electrolytes, separated by ion or proton exchange membrane in which electrolyte flows through one or more electrochemical cells from one or more tanks (Charging and discharging of batteries occur by ion transferring from one component to another component through the membrane). The energy capacity is a function of the electrolyte volume, and the power is a function of the surface area of the electrodes, the biggest advantages of Flow Batteries are the capability of pack in large volumes, which allows for cheap large-scale (GWh) energy storage using large basins. (Refer to the Secondary Battery (or Rechargeable Battery))
