A modeling framework developed at MIT can help speed the development of flow batteries for large-scale, long-duration electricity storage on the future grid. In the coming decades, renewable energy sources such as solar and wind will increasingly dominate the conventional power grid.
Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell. The power each cell generates depends on the current density and voltage. Flow batteries have typically been operated at about 50 mA/cm 2, approximately the same as batteries without convection.
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.
Also, note that as the volume of the cell components gets small relative to the volume of the electrolytes, the flow battery approaches its theoretical maximum of energy density. Higher capacity systems are thus more efficient in this respect, as the majority of the weight is the electrolyte which directly stores energy.
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.
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.
