AI Customer ServiceHere’s how our vanadium flow batteries work. The fundamentals of VFB technology are not new, having been first developed in the late 1980s. In contrast to lithium-ion batteries which store electrochemical energy in solid forms of lithium, flow batteries use a liquid electrolyte instead, stored in large tanks.
Vanadium redox flow battery (VRFB) energy storage systems have the advantages of flexible location, ensured safety, long durability, independent power and capacity configuration, etc., which make them the promising contestants for power systems applications.
The vanadium redox flow battery is one of the most promising secondary batteries as a large-capacity energy storage device for storing renewable energy [1, 2, 4]. Recently, a safety issue has been arisen by frequent fire accident of a large-capacity energy storage system (ESS) using a lithium ion battery.
The structure is shown in the figure. The key components of VRB, such as electrode, ion exchange membrane, bipolar plate and electrolyte, are used as inputs in the model to simulate the establishment of all vanadium flow battery energy storage system with different requirements (Fig. 3 ).

Other useful properties of vanadium flow batteries are their fast response to changing loads and their overload capacities. They can achieve a response time of under half a millisecond for a 100% load change, and allow overloads of as much as 400% for 10 seconds. Response time is limited mostly by the electrical equipment.
