Technical FAQs 4

Are flow batteries better than traditional energy storage systems?

Flow batteries offer several advantages over traditional energy storage systems. One key advantage is that the energy capacity of a flow battery can be increased by enlarging the electrolyte tanks, making it ideal for large-scale applications such as grid storage.

What is a flow battery?

A flow battery is a type of rechargeable battery that stores energy in liquid electrolyte solutions contained within tanks. Unlike traditional lithium-ion or lead-acid batteries, flow batteries offer longer life spans, scalability, and the ability to discharge for extended durations.

How long do flow batteries last?

Flow batteries can last for decades with minimal performance loss, unlike lithium-ion batteries, which degrade with repeated charging cycles. They use non-flammable liquid electrolytes, reducing the risk of fire or explosion.

Can a flow battery be expanded?

The energy storage capacity of a flow battery can be easily increased by adding larger tanks to store more electrolyte. This is a key advantage over solid-state batteries, like lithium-ion, where scaling up often requires more complex and expensive modifications.
