Their work focuses on this electrochemical cell, which looks promising for grid-scale energy storage—except for one problem: Current flow batteries rely on vanadium, an energy-storage material that’s expensive and not always readily available.

What are flow batteries?

While you may be familiar with traditional battery types such as lead-acid, Ni-Cd and lithium-ion, flow batteries are a lesser-known but increasingly important technology in the energy storage sector.

What is a true flow battery?

Other true flow batteries might have a gas species (e.g., hydrogen, chlorine) and liquid species (e.g., bromine). Rechargeable fuel cells like H2-Br2 and H2-Cl2 could be thought of as true flow batteries.
