Are flow batteries scalable?

Scalability: One of the standout features of flow batteries is their inherent scalability. The energy storage capacity of a flow battery can be easily increased by adding larger tanks to store more electrolyte.

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.

Are flow batteries more scalable than lithium-ion batteries?

Scalability: Flow batteries are more easily scalable than lithium-ion batteries. The energy storage capacity of a flow battery can be increased simply by adding larger tanks to store more electrolyte, while scaling lithium-ion batteries requires more complex and expensive infrastructure.
