Table I. Characteristics of Some Flow Battery Systems. the size of the engine and the energy density is determined by the size of the fuel tank. In a flow battery there is inherent safety of storing the active materials separately from the reactive point source.
The energy capacity requirement of a flow battery is addressed by the size of the external storage components. Consequently, a redox flow battery system could approach its theoretical energy density as the system is scaled up to a point where the weight or volume of the battery is small relative to that of the stored fuel and oxidant.
Fig. 1. Power and energy densities of various EES systems. A flow battery is an electrochemical device that converts the chemical energy in the electro-active materials directly to electrical energy, similar to a conventional battery and fuel cells.
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.
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.
Other true flow batteries might have a gas species (e.g., hydrogen, chlorine) and liquid species (e.g., bromine). Rechargeable fuel cells like H2-Br2 and H2-Cl2 could be thought of as true flow batteries. Systems in which one or more electro-active components are stored internally are called hybrid flow batteries.
