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.
If one or more electro-active components are deposited as a solid layer, the system is known as a hybrid flow battery, that is, the electrochemical cell contains one battery electrode and one fuel cell electrode.
Various flow battery systems have been investigated based on different chemistries. Based on the electro-active materials used in the system, the more successful pair of electrodes are liquid/gas-metal and liquid-liquid electrode systems.
A flow battery stores energy in two soluble redox couples, which are comprised of exterior liquid electrolyte containers. During charging, one electrolyte is oxidized at the anode, while during discharging, another electrolyte is reduced at the cathode. In this way, the electrical energy is transferred to the electrolyte.
