All vanadium liquid flow battery is a kind of energy storage medium which can store a lot of energy. It has become the mainstream liquid current battery with the advantages of long cycle life, high security and reusable resources, and is widely used in the power field. The vanadium redox flow battery is a “liquid-solid-liquid” battery.
At a constant electrolyte solution volume, increasing the vanadium ions concentration increases interconversion between VO 2+ and VO 2+ and between V 3+ and V 2+ at the positive and negative electrodes, respectively, which in turn leads to longer charge and discharge times. Fig. 5.
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 ion exchange membrane not only separates the positive and negative electrolytes of the same single cell to avoid short circuits, but also conducts cations and/or anions to achieve a current loop, which plays a decisive role in the coulombic efficiency and energy efficiency of the vanadium redox flow battery.
