The electrolyte of the all-vanadium redox flow battery is the charge and discharge reactant of the all-vanadium redox flow battery. The concentration of vanadium ions in the electrolyte and the volume of the electrolyte affect the power and capacity of the battery. There are four valence states of vanadium ions in the electrolyte.
The electrode of the all-vanadium flow battery is the place for the charge and discharge reaction of the chemical energy storage system, and the electrode itself does not participate in the electrochemical reaction.
