Different oxidation states of dissolved vanadium ions in the electrolyte store or deliver electric energy. The electrolyte is continuously fed from a tank system into the reaction cell (also called Stack). Depending on the current demand, energy is stored in the electrolyte (battery charging) or fed into the grid/network (battery discharging).
Vanadium flow batteries are one of the most promising technologies for large-scale energy storage, due to their long cycle life, excellent recyclability, and low fire risk. However, their uptake is largely limited due to their low energy densities compared to lithium-ion technology as well as high upfront cost.
