Vanadium Redox Flow Battery
The vanadium redox flow battery is a technology characterized by the redox reactions of different ionic forms of vanadium [11]. As the electrolyte tanks and power stacks are separated, the energy capacity of these batteries can be increased or reduced based on the tanks'' volume, while the power capacity depends on the number of cells in the power stacks.
