The vanadium redox flow battery is generally utilised for power systems ranging from 100kW to 10MW in capacity, meaning that it is primarily used for large scale commercial projects. These batteries offer greater advantages over alternate technologies once they are deployed at greater scale. As they often require large amounts of space, they have been proposed as an ideal battery technology to provide continuous and backup power to the grid.

Zinc-bromine Flow Battery

The Zinc-bromine flow battery is the most common hybrid flow battery variation. The zinc-bromine still has the cathode & anode terminals however, the anode terminal is water-based whilst the cathode terminal contains bromine in a solution. Zinc metal is plated on the anode terminal creating a charge by forming the electrochemical stack which stores energy. This zinc metal is oxidised during discharge, two electrons are released to the cathode to facilitate the soluble bromide ions. The generated electric current increases the zinc-ion and bromide-ion concentration in both terminals.
