The vanadium redox flow battery (VRFB) is one promising candidate in large-scale stationary energy storage systems. It stores electric energy by changing the oxidation numbers of anolyte and catholyte through redox reaction.
Vanadium redox flow battery is one of the most promising devices for a large energy storage system to substitute the fossil fuel and nuclear energy with renewable energy. The VRFB is a complicated device that combines all the technologies of electrochemistry, mechanical engineering, polymer science, and materials science similar to the fuel cell.
Based on the equivalent circuit model with pump loss, an open all-vanadium redox flow battery model is established to reflect the influence of the parameter indicators of the key components of the vanadium redox battery on the battery performance.
The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers.
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.
