Are iron flow batteries better than Li-ion batteries?

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.

What are the typical chemistries used in flow batteries?

Typical flow battery chemistries include all vanadium, iron-chromium, zinc-bromine, zinc-cerium, and zinc-ion. A flow battery is an electrochemical cell that converts chemical energy into electrical energy as a result of ion exchange across an ion-selective membrane that separates two liquid electrolytes stored in separate tanks.

What makes iron flow batteries environmentally friendly?

As iron flow batteries consist of earth-abundant and non-toxic materials, they are environmentally friendly, safe, and one of the most reliable electrochemical energy storage devices. On the other hand, an iron flow battery uses electrolytes made up of iron salts in an ionized form.
