Technical FAQs 4

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.

Are flow batteries suitable for large-scale energy storage?

Flow batteries have long been considered as a competitive candidate for large-scale energy storage owing to their advantages of high power density, long lifespan, and decoupling of energy density/power. However, high membrane and maintenance costs hinder their further development and application.

What are the main types of flow batteries?

The two most common types of flow batteries are redox flow batteries (e.g. vanadium flow batteries) and hybrid flow batteries.

Are flow batteries flammable?

Flow batteries use non-flammable liquid electrolytes, reducing the risk of fire or explosion. This is a critical advantage in high-capacity systems. Many flow batteries, such as vanadium-based systems, use materials that can be recycled, reducing their environmental impact.
