The VRFB energy storage system consists of stacks, positive and negative electrolyte, pipeline system (including circulating pumps, flowmeters, temperature sensors), energy conversion system, monitoring system, etc. The stack is the energy conversion device and the most important and complex part of a VRFB system.
However, as the flow rate increases, the pumping loss increases significantly, resulting in an overall energy loss in the VRFB energy storage system. Fig. 4 (a) also discusses the relationship between pressure drop of the 10-stack and the flow rate of electrolyte.
Working conditions induced performance of the large-scale stack are discussed. 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.
Compared with pumped storage, VRFB has a more flexible location and a shorter construction period. While compared with lithium battery, VRFB is safer so that can be utilized in densely populated urban areas.
According to the working principle of VRFB, after the electrolyte is pumped into the stack through the peristaltic pump and pipeline system, it needs to flow according to the internal flow channel of the flow frames and flow through the electrode to complete the electrochemical reaction inside the battery.
However, the engineering technological development also plays a fundamental role in view of the successful application of VRFB in large plants. A battery module is typically an array of kW-scale stacks arranged in a desired series-parallel combination and hence, the kW-scale stack is the fundamental unit of the battery module .
