Zinc-Iron Flow Battery Manufacturer

The zinc-iron flow battery technology was originally developed by ViZn Energy Systems. Image: Vizn / WeView. Shanghai-based WeView has raised US$56.5 million in several rounds of financing to commercialise the zinc-iron flow battery energy storage systems technology originally developed by ViZn Energy Systems.

With over 40 years of experience in research and development, WeView's zinc-iron flow batteries offer distinct advantages, including inherent safety, long-duration energy storage, low cost, environment-friendly, flexible in location, short construction period, and long lifespan.

An iron flow battery uses electrolytes made up of iron salts in an ionized form. These batteries are environmentally friendly, safe, and one of the most reliable electrochemical energy storage devices due to their earth-abundant and non-toxic materials.

Zinc-iron flow batteries are non-explosive, non-flammable, non-toxic, recyclable at the end of their life, and made from globally abundant materials. These batteries are suitable for utility-scale wind and solar applications. The US-based ViZn Energy Systems develops and produces flow batteries that experience zero capacity fade over 20 years.

A zinc-bromine flow battery is a type of hybrid flow battery, where zinc bromide electrolyte and metallic zinc are stored in two tanks. The advantages of this energy storage include 100% depth of discharge capability on a daily basis, high energy density, scalability and no shelf life limitations as zinc-bromine batteries are non-perishable.

Iron flow batteries have a longer asset life than Li-ion batteries. Battery manufacturers are collaborating with utility companies to implement iron flow battery projects, aiming to replace diesel-fueled power generation with the more environmentally friendly flow battery system.
