In numerous energy storage technology, vanadium redox flow batteries (VRFBs) are widely concerned by all around the world with their advantages of long service life, capacity and power independent design [9, 10].
Battery storage systems are becoming increasingly important to meet large demands during peak energy consumption, especially with the growing supply of intermittent renewable energy. The vanadium redox flow battery systems are attracting attention due to their scalability and robustness, making them highly promising.
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 most promising, commonly researched and pursued RFB technology is the vanadium redox flow battery (VRFB) . One main difference between redox flow batteries and more typical electrochemical batteries is the method of electrolyte storage: flow batteries store the electrolytes in external tanks away from the battery center .
The vanadium redox flow battery is mainly composed of four parts: storage tank, pump, electrolyte and stack. The stack is composed of multiple single cells connected in series. The single cells are separated by bipolar plates.
