The chemical energy is converted to the electric energy when the electrolytes flow through the external tanks. The volume of the electrolyte and the surface area of the electrode influence the performance of the flow battery. Flow batteries can be employed both as a rechargeable secondary battery and a fuel cell.
A typical flow battery has been shown in Fig. 8. Some of the main characteristics of flow batteries are high power, long duration, and power rating and the energy rating are decoupled; electrolytes can be replaced easily . Fig. 8. Illustration of flow battery system [133,137]. Zhibin Zhou, ...
The capacity is a function of the amount of electrolyte and concentration of the active ions, whereas the power is primarily a function of electrode area within the cell. Similar to lithium-ion cells, flow battery cells can be stacked in series to meet voltage requirements. However, the electrolyte tanks remain external to the system.
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.
The charge neutrality condition for the each half-cell is maintained by a selective ion exchange membrane separating the anode and cathode compartments. The key differentiating factor of flow batteries is that the power and energy components are separate and can be scaled independently.
Since capacity is independent of the power-generating component, as in an internal combustion engine and gas tank, it can be increased by simple enlargement of the electrolyte storage tanks. Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell.
