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.
Several factors contribute to the adoption of vanadium flow batteries, including the need for energy storage in renewable energy integration, reductions in energy costs, and technological advancements in battery components. The scalability of these systems also impacts their deployment.
The key advantages of using vanadium flow batteries for energy storage include their longevity, scalability, safety, and efficiency. Longevity: Vanadium flow batteries have a long operational life, often exceeding 20 years. Scalability: These batteries can be easily scaled to accommodate various energy storage needs.
Vanadium flow batteries (VFBs) offer distinct advantages and disadvantages compared to other energy storage technologies like lithium-ion batteries and pumped hydro storage, primarily in cycles, lifespan, and safety.
While vanadium flow batteries can cycle through charge and discharge many times, issues such as membrane degradation can shorten their effective life. A lifespan of around 10,000 cycles is common, unlike lithium-ion batteries, which can offer around 3,000 to 5,000 cycles.
Minimal Degradation: Vanadium flow batteries experience little degradation over time. Their unique chemistry allows the active material to remain stable and functional throughout numerous charge and discharge cycles. Research indicates that this characteristic contributes to the long lifespan and reliability of the technology (Lu et al., 2015).
