How the Vanadium Redox Flow Battery "VRFB" Works

Learn about the VRB, VRFB from the inventor of the vanadium redox battery and Advisory Board Member of VanadiumCorp, Dr. Maria Skyllas-Kazacos Professor Emeritus, University of New South Wales.

VRFBs are containerized, long duration, non-flammable, compact, reusable over infinite cycles and last more than 20 years. Most batteries use two chemicals that change valence (or charge or redox state) and cross-contaminate and thus degrade over time. VRFBs utilize multiple valence states of vanadium as a single element to store and release charge. VRFBs consists of two tanks of vanadium electrolyte that flow adjacent to each other past a membrane and generate a charge by moving electrons back and forth during charging and discharging. This battery offers unlimited energy capacity simply by using larger electrolyte storage tanks. It can be left completely charged for long periods without losing power and maintenance is much simpler than other batteries. The unique advantage to separate power and energy also provides significant advantages over competing technologies. With sustainably produced VanadiumCorp Electrolyte™, the carbon footprint of the VRFB is remarkably low.

The team of industry veterans at VanadiumCorp are pioneering advancements and commercializing a new generation of VRFB systems with higher performance, efficiencies and increased function.

Mass commercialization of VRFBs has long been inhibited by the pollutive and inefficient production methods of the past. VanadiumCorp changing that by commercializing patented recover vanadium from many source including waste. The resultant vanadium that makes up most of a VRFB system can therefore be green in how it is made and green in how its used.

Further to this, Vanadiumcorp also wholly owns one of the most significant vanadium mineral resources world in Quebec Canada named Lac Dore. Very few vanadium resources are capable of meeting the demand of the high purity vanadium market that includes vanadium redox batteries. The primary supply of high purity vanadium requires vanadium rich magnetite resources that have exceptional metallurgy and low impurities. In the early 2000s. Pilot production of battery-grade vanadium from the Lac Dore project was utilized successfully by Sumitomo in VRFB systems.

What sets VanadiumCorp apart is our integrated advantage and exceptional resource base. All of our resources are wholly-owned and strategically located in Quebec Canada close to infrastructure with mineralization accessible at surface. Our mineral resources and process technology that unlocks new supply are both aimed at the creation of stable supply for clean energy storage technology of the VRFB. A battery that can be good for the planet in every way with VanadiumCorp.
