VRFBs are a type of rechargeable battery that stores energy in liquid electrolytes. [5] The battery uses vanadium's ability to exist in a solution in four different oxidation. . Energy storage systems are used to regulate this power supply, and Vanadium redox flow batteries (VRFBs) have been proposed as one such method to support grid integration.

During the charging process, an ion exchange happens across a membrane. This process changes the oxidation states of the vanadium ions, leading to efficient electricity. . China's Dalian Flow Battery Demonstration Project proves it – their 200MW/800MWh system has powered 200,000 homes since 2022. However, the development of VRFBs is hindered by its limitation to dissolve diverse. .
