6 FAQs about [Charging principle of liquid flow energy storage battery]

How a flow battery works?

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.

How does a flow battery differ from a conventional battery?

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.

Can flow batteries be used as a fuel cell?

Flow batteries can be employed both as a rechargeable secondary battery and a fuel cell. The earlier loaded electrolyte will be the alternative for the discharged electrolyte and thus it has the synergic significance.

What is the difference between power and capacity of a flow battery?

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.

How do flow batteries increase power and capacity?

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.

Why is a flow battery more efficient?

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.
