The electrochemical cells can be electrically connected in series or parallel, so determining the power of the flow battery system. This decoupling of energy rating and power rating is an important feature of flow battery systems. The interconversion of energy between electrical and stored chemical energy takes place in the electrochemical cell.
Flow batteries offer several advantages over traditional energy storage systems: The energy capacity of a flow battery can be increased simply by enlarging the electrolyte tanks, making it ideal for large-scale applications such as grid storage.
Volume of electrolyte in external tanks determines energy storage capacity Flow batteries can be tailored for an particular application Very fast response times- < 1 msec Time to switch between full-power charge and full-power discharge Typically limited by controls and power electronics Potentially very long discharge times
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.
Pumps are critical components that circulate the electrolytes from the storage tanks to the electrochemical cell and back. This circulation is essential for maintaining consistent energy flow during charging and discharging cycles. Flow batteries operate through two primary processes: charging and discharging.
