An important feature of vanadium redox flow batteries is the independent sizing of their power and energy rating. Energy capacity, which depends on a reactant concentration and electrolyte volume, and power, which depends on the area of electrode and the number of cells in a stack, can be independently optimized to suit specific user requirements.
