Flow batteries can be employed both as a rechargeable secondary battery and a fuel cell. The earlier loaded electrolyte will be the alternative for the discharged electrolyte and thus it has the synergic significance.
True flow batteries have all the reactants and products of the electro-active chemicals stored external to the power conversion device. Systems in which all the electro-active materials are dissolved in a liquid electrolyte are called redox (for reduction/oxidation) 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.
