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.

Chinese scientists have achieved a breakthrough in “all-iron flow battery” technology that could sharply reduce the cost of storing renewable energy while significantly extending battery lifespan. Lithium costs over 80 times more than iron as a raw industrial material at present. Iron-flow batteries address these challenges by combining the inherent advantages of redox flow technology with the cost-efficiency of iron. Unlike solid-state batteries, flow batteries separate energy storage from power delivery, allowing for independent scalability, longer lifetimes, and reduced. A research team at the Institute of Metal Research of the Chinese Academy of Sciences (CAS) has advanced “all-iron” flow battery technology.
