Vanadium redox flow battery (VRFB), in which vanadium is used as active energy storage material on both positive and negative sides, is perhaps the most developed redox flow battery (RFB) for large-scale renewable energy storage integrated into the electricity grid as compared to other types of RFBs [1, 2, 3, 4, 5].

What is a vanadium redox battery (VRB)?

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 which employs vanadium ions as charge carriers.

What are vanadium redox batteries used for?

For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids. Numerous companies and organizations are involved in funding and developing vanadium redox batteries. Pissoort mentioned the possibility of VRFBs in the 1930s.
