Technical FAQs 4

How do vanadium flow batteries work?

Here’s how our vanadium flow batteries work. The fundamentals of VFB technology are not new, having been first developed in the late 1980s. In contrast to lithium-ion batteries which store electrochemical energy in solid forms of lithium, flow batteries use a liquid electrolyte instead, stored in large tanks.

Are vanadium flow batteries better than lithium-ion batteries?

Vanadium flow batteries are gaining attention in the media, various industries, and even the general public for the many benefits over lithium-ion batteries. Those benefits include longer life, very little degradation of performance over time, and a much wider operating temperature range. All of which significantly reduces the cost of ownership.

Are vanadium flow batteries safe?

The report highlights that thermal runaway remains a critical risk and that 72% of system-level defects involve fire safety components. In contrast, vanadium flow batteries, which are non-flammable and thermally stable by design, offer a safer and more predictable option for stationary energy storage applications.

Are vanadium flow batteries recyclable?

With vanadium flow batteries, all parts and components have a recyclability factor close to 100%. The electrolyte can be processed and reused; 100% of the vanadium can be extracted and reused for other applications with no impact on primary mining. Also, these batteries contain no toxic metals such as lead, cadmium, zinc, and nickel.
